Find x.

answer choices
7
7√2
√14

x=7

Step-by-step explanation:

This is a right triangle, we can use sin , cos, and tan

tan theta = opposite side/ adjacent

tan 45 = 7/x

Multiply each side by x

x tan 45 = 7/x *x

x tan 45 =7

Divide each side by 45

x tan 45 / tan 45 = 7/ tan 45

x = 7 / tan 45

x =7

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
