how do i solve this ik the answer is 10 though

Answer:

both = - [tex]\frac{\sqrt{2} }{2}[/tex]

Step-by-step explanation:

[tex]\frac{5\pi }{4}[/tex] is an angle in the 3rd quadrant where both sin and cos < 0

The related acute angle is [tex]\frac{\pi }{4}[/tex] , then

cos ([tex]\frac{5\pi }{4}[/tex] ) = - cos ([tex]\frac{\pi }{4}[/tex] ) = - [tex]\frac{1}{\sqrt{2} }[/tex] = - [tex]\frac{\sqrt{2} }{2}[/tex]

sin ( [tex]\frac{5\pi }{4}[/tex] ) = - sin ([tex]\frac{\pi }{4}[/tex] ) = - [tex]\frac{1}{\sqrt{2} }[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex]

Answer:

6. x = 16

7. n = -11

Step-by-step explanation:

6. -7(x-6)=-70

= -7x + 42 = - 70

= - 7x = - 70 - 42

= -7x = -112

= -7x/-7 = -112-/7

= x = 16.

7. 9 + n= - 2

= n= -2 - 9

= n = -11

Answer:

37° and 143°

Step-by-step explanation:

Hi there!

These labeled angles are corresponding angles, meaning they have a sum of 180 degrees (we can tell because the line segments they join make a "C" shape).

Knowing this, we can construct the following equation to solve for x:

[tex](-13x+39)+(-4x+5)=180[/tex]

Open up the parentheses

[tex]-13x+39-4x+5=180[/tex]

Combine like terms

[tex]-17x+44=180[/tex]

Subtract 44 from both sides to isolate -17x

[tex]-17x+44-44=180-44\\-17x=136[/tex]

Divide both sides by -17

[tex]\frac{-17x}{-17} =\frac{136}{-17}\\x=-8[/tex]

Therefore, x is equal to -8. Now, use this to find the measure of each angle:

[tex]-4x+5\\= -4(-8)+5\\= 32+5\\= 37[/tex]

[tex]-13x+39\\= -13(-8)+39\\= 104+39\\=143[/tex]

(Alternatively, we can solve for one angle and then subtract it from 180 to solve for the other angle.)

I hope this helps!

Answer:

17.3 / [tex]\frac{52}{3}[/tex] / 17[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

you divide 13 and [tex]\frac{3}{4}[/tex]: 13 ÷[tex]\frac{3}{4} \\[/tex]

[tex]\frac{13}{1}[/tex]×[tex]\frac{4}{3}[/tex]=[tex]\frac{52}{3}[/tex]

simplify and you get 17.3 or 17[tex]\frac{1}{3}[/tex]

Answer:

15^2 + 36^2 = c^2

225+1296 = c^2

sqrt(1521) = sqrt(c)

c = 39

1st Blank - 15

2nd Blank - 2

3rd Blank - 225

4th Blank - 1296

5th Blank - 1521

6th Blank  - c

7th Blank - 39

Step-by-step explanation:

Using the pythagorean theorem we know a^2+b^2=c^2 so by filling out a and b into the blanks we then know the sum of a and b squared is equal to c squared then to cancel out the exponent we use the radical then find c is equal to 39.

Answer:

1. 15^2 + 36^2=c^2

2. 225 + 1296=c^2

3. sqrt (15^2 36^2)=sqrt (c^2)

Good Day!

A pair of complementary angles as shown in the protractor is angles DEH & HEJ; option D.

Complementary angles are two angles whose sum is equal to 90°.

The angles that are complementary as shown in the protractor are DEH and HEJ.

DEH = 75

HEJ = 15

DEH + HEJ = 90°.

Therefore, a pair of complementary angles as shown in the protractor is angles DEH & HEJ.

The required answers by solving two-step equations are:

Q1. The solution of equation 1 - 7b = -20 is b = 3

Q2. The solution of equation -k - 5 =20 is k = -5

Q3. The solution of equation-1 + 8a = -129 is a = -16

Q1. Solve 1 - 7b = -20

To solve this equation, we will isolate the variable b by performing two steps.

Step 1: Subtract 1 from both sides of the equation:

1 - 1 - 7b = -20 - 1

-7b = -21

Step 2: Divide both sides of the equation by -7 to solve for b:

(-7b) / -7 = (-21) / -7

b = 3

Therefore, the solution to the equation 1 - 7b = -20 is b = 3.

Q2. Solve -k - 5 = 0

To solve this equation, we will isolate the variable k by performing two steps.

Step 1: Add 5 to both sides of the equation:

(-k) - 5 + 5 = 0 + 5

-k = 5

Step 2: Multiply both sides of the equation by -1 to solve for k:

(-k) * (-1) = 5 * (-1)

k = -5

Therefore, the solution to the equation -k - 5 = 0 is k = -5.

Q3. Solve -1 + 8a = -129

To solve this equation, we will isolate the variable a by performing two steps.

Step 1: Add 1 to both sides of the equation:

(-1) + 1 + 8a = -129 + 1

8a = -128

Step 2: Divide both sides of the equation by 8 to solve for a:

(8a) / 8 = (-128) / 8

a = -16

Therefore, the solution to the equation -1 + 8a = -129 is a = -16.

Therefore, the required answers by solving two-step equations are:

Q1. The solution of equation 1 - 7b = -20 is b = 3

Q2. The solution of equation -k - 5 =20 is k = -5

Q3. The solution of equation-1 + 8a = -129 is a = -16
