Question

7. what is the value of x

Answer 1

Answer:

x = 18.5

Step-by-step explanation:

tangent is opposite over adjacent

tan 51 = x/15

solve for x

be sure your calculator is in Degree mode.

x = tan 51 * 15

Answer 2

Answer:

x ≈ 18.52

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan51° = $\frac{opposite}{adjacent}$ = $\frac{x}{15}$

Multiply both sides by 15

15 × tan51° = x, thus

x ≈ 18.52 ( to 2 dec. places )
