Simplify |−3 − 8|
A. –11

B. –5

C. 5

D. 11

Here we can see there is modulus so

while doing calculation

| -3-8 |

| -11 |

Here it is modulus so - changes into +

so it's answer is 11.

df =

both have same length

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
