Answer:

x = 52

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles of a triangle

x+72 = 34+90

x +72 =124

Subtract 72 from each side

x = 124-72

x =52

Answer:

x = 52 degrees

Step-by-step explanation:

Let's first focus on the angle x + 72.  Immediately adjacent to x + 72 is angle RQS.  These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees.  Then angle RQS can be expressed as

180 degrees - (x + 72 degrees), or 108 - x degrees.

The three interior angles of the triangle must add up to 180 degrees.  Hence

108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:

108 - x + 34 = 90

This yields x = 52 degrees.

Answer:

variables is the correct answer

Answer:

ALL OF THE ABOVE

Step-by-step explanation:

An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.

It can be all of the above too. because everything is needed to make an expression.

2 and 4 are vertical angles

Answer: The answer to Number 4 is 1!

Step-by-step explanation:

First you solve for the numbers in parentheses. 16 - 7 is 9, and 2 x 4 is 8. Then you solve for the remaining numbers. So 9 - 8 is indeed 1.

Hope this helps! :)

Answer:

have a good day :)

Step-by-step explanation:

vertical means they are right across from each other

Answer:

The numbers are 8 and 6

Step-by-step explanation:

Let x and y be the two numbers

x+y = 14

x-y = 2

Add the two equations together

x+y = 14

x-y = 2

--------------

2x +0y = 16

Divide by 2

2x/2 = 16/2

x = 8

Now find y

x+y = 14

8+y =14

Subtract 8 from each side

8+y-8 =14-8

y =6

The numbers are 8 and 6

Answer:

8 and 6

Answer:

x = 5

Step-by-step explanation:

Pythagorean Theorem:

a² + b² = c²

12² + b² = 13²

144 + b² = 169

b² = 25

b = 5

Answer:

C. y = 1/2x + 5

Step-by-step explanation:

For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.

For D. it doesn't even have x in it, so basically y equals a number.

C. is a linear equation, y = 1/2x + 5

5. an increase and then decrease; the spike in visitors could be because of the start of summer

6. December is around Christmas, where most people would have holiday

Answer:

2) 3/4 of the girls did not have 1 piece bathing suits

3) 4/6 were at the kiddie pool

4) 1/3 was boys

sorry if this was wrong

Answer:

D.11 in

Step-by-step explanation:

isosceles triangles have two congruent sides

The missing side length is congruent with the longer side ( this is pretty obvious )

If the longer side has a length of 11in and the missing side is congruent to the longer side then the missing side length equals 11 in

Answer:

4. alternate exterior angles

5. 4.5

Answer:

a-45

b-30

c-90

Step-by-step explanation:

blue shape-90 degree angle

pink is 45 since 2 make up a quadrant

aqua is 30 because half 2 quadrants equal 180.

180-(45x2)=90

90/3=30

hope this helps!

Answer:

He should have multiplied 15 tsp by 1 tbsp/3tsp.

Step-by-step explanation:

The tsp labels cancel each other out when one is the numerator and one is the denominator.

15tsp x 1 tbsp/3tsp = 15/3 = 5 tbsp

Answer:

17

Step-by-step explanation:

Substitute "x" for "5" in the equation

3(5) + 2

15 + 2

17

Answer:

3x + 2 = 17

Step-by-step explanation:

x = 5

3x + 2

plug in 5 for x

3(5) + 2

multiply

15 + 2

add

17

Therefor

3x + 2 = 17

-1/4

This will remain its absolute value

Answer:

absolute value is the oppistie of the number so if it is positive is will turn negative so i think the answer is C

Answer:

We know the width maybe 22ft and at its widest.

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.

With triangles;

The number of triangles is always 2 less than that that of its sides.

= 3 triangles + 2 = 5 sides.

The sum of interior angles

(n-2) x 180 = 540 degree

5-2 x 180

To determine the amount of sides; we remember

(n-2) 180

360 = (n-2) 180

+360 = 180 -360 +180

+360 = 180 = (3 triangles with 180)

900/180 = 5 sides.

If we say 5 triangles created with 3 given lengths

then same rule applies n-2 (180)

=7 sides

= if regular shape largest line 22 x 7 = 154 ft sq = Area.

Answer:

374

Step-by-step explanation:

First do the area of the triangle 7 x 22 = 308 308/2 = 154 22 x 10 = 220 220+154 =374

Answer:

C. $133.96

Step-by-step explanation:

Convert units:

12 · 0.305 = 3.66 m

8 · 0.305 = 2.44 m

Find the area of the room:

3.66 m · 2.44 m = 8.9304 m²

Find the cost:

8.9304 · 15 = 133.96

Answer:

12

Step-by-step explanation:

We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.

Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520

So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3

Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.

We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or

11,520/(40*24) = 11,520/960 = 12

Her chest is 12 inches wide
