Guys please help me find the answer

Answer:

133

Step-by-step explanation:

I am added all the degrees

Given:

Length of ladder = 4.5 meters

Length between ladder and wall = 1.2 meter

To find:

If the angle of the ladder is between 74° - 76°

Steps:

We know,

cos(x) =  [tex]\frac{adjacent}{hypotenuse}[/tex]

Here 'x' is the angle of the ladder. Substituting the values,

[tex]cos(x) = \frac{1.2}{4.5}[/tex]

[tex]x = cos^{-1}(\frac{1.2}{4.5} )[/tex]

[tex]x = cos^{-1}(0.2666)[/tex]

Now we can either use natural cos table or use aa calculator, i am going to use the calculator but if you want to know how to do it with the table, pls comment to this answer.

x = 74.533°

Since x > 74° and x < 76°, it is safe for work

Therefore, the angle is in the safe position for Bryan to use

Happy to help :)

Answer: 10

Step-by-step explanation:

So since this is all about perimeter you just got to add the values together. So lets use 12 as the denominator for every fraction. 1/4 is equal to 3/12 and 2/3 is equal to 8/12. So in conclusion 3/12 plus 8/12 and 1/12 will equal 1 in total. and then add up all the whole numbers 4 + 2 + 3 + 1 will get you 10. So 10 is your answer.

Answer:

36°, 36°, 108°

Step-by-step explanation:

let the 2 congruent base angles of the isosceles triangle be x

Then the vertex angle is 3x

Sum the angles and equate to 180 ( angle sum of triangle )

x + x + 3x = 180

5x = 180 ( divide both sides by 5 )

x = 36 , then

3x = 3 × 36 = 108

The angles are 36°, 36° and 108°

Answer:

x = ± 10

Step-by-step explanation:

To solve the equation let y = 0 , that is

0 = 100 - x²( add x² to both sides )

x² = 100 (I take the square root of both sides )

x = ± [tex]\sqrt{100}[/tex] = ± 10

Then solution is x = - 10, x = 10

Answer:

Sales price: $1,575 Discount: $175

Step-by-step explanation:

To find the sales price, you either multiply the percent(indecimals, so 10% would be .1) by the discount price, but be careful to subtract original by new.

To get the anwser right away, multiply the price you have to pay, 90%, so .9 by 1,750. You get $1,575.

To get the discount, subtract original by new, $1750-$1575=$175

Answer:

The third graph is precise

Step-by-step explanation:

-2 > n ≥ 4

n<-2 or n≥4 compound inequality is represented in the third graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given inequality is n<-2 or n≥4

The third number line represents the inequality  n<-2 or n≥4.

The open circle at -2 indicates that n is not included in the solution set, since the inequality is strict.

The closed circle at 4 indicates that n is included in the solution set, since the inequality is not strict.

Hence, n<-2 or n≥4 compound inequality is represented in the third graph.

[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

Answer:

-6, 0

Step-by-step explanation:

since the first question is a inverse function, the -15 isn't an x value anymore so it is a y.

the second question is the same thing for the 4 because it is an inverse function. so that would be -11, and the function of 9 you would look at the x value of 9 and find the corresponding y, which 11. so -11+11 =0

Answer:

Step-by-step explanation:

so we know a few things about t his triangle,  it's a special one  :P  ,   it's called isosceles because  two of the legs are the same length, which also mean that the angle x  is the same at the other unknown angle sooo  there are  2 x's   if that makes sense?  and then we can solve this , b/c we also know that the interior angles of a triangle add up to 180°

180 = 32 + 2x

148 = 2x

74 =x

∠x = 74°

Answer:

It's a combination, BUT...

Step-by-step explanation:

Definition: A combination is a grouping of outcomes in which the order does not matter. That's the difference between combination and permutation.

Combination Formula: nCr = (n!)/[r!(n-r)!)] where n stands for number of things and r the pair chosen

Applied to this case: We have n=5 (12345) and r=5 for the 5-digit lock combination.

5C5 = (5!)/[5!(5-5)] = 1

But!! As you can see, we cannot have 1 possible combinations so.. We have to assume that this is a permutation!!! Conceptually, this looks pretty much like a combination, but being the same range as number of items, we conclude that it's a permutation.

Permutation Formula: nPr = (n!)/(n-r)!

nPr = (5!)/(5-5)! = 120

Well, this looks way more accurate now, right?

Final Answer: The scenario involves a permutation, and there's 120 possible combinations of those 5 numbers in a 5-digit lock.
