Question

Tommy was solving the triangle below. Which of the following is TRUE about his solution? Help ASAP !!!!

Answer 1

Answer:

The value of x is incorrect he should be using 28/21 instead of 21/28

Step-by-step explanation:

tan = opp/adj

tanx = 28/21

The value of x is incorrect he should be using 28/21 instead of 21/28

Answer 2

Answer:

A) The value of x is incorrect. He should be using 28/21 instead of 21/28.

Step-by-step explanation:

Recall that $tan\theta=\frac{opposite}{adjacent}$. This means that the correct setup would be $tan\theta=\frac{28}{21}$ since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be $x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o$
