Question

Find x. Answer choices 7 7√2 √14

Answer 1

Answer:

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
