Question 1:
We are even an angle of depression in this diagram. The interior angle of the triangle that is adjacent to x is 90-20, or 70 degrees.
We can use the tangent to solve for this question. Divide 15 by the tangent of 70 degrees.
[tex]\approx 5.5[/tex]
[tex]\dfrac{15}{ \tan(70)}[/tex]
Your answer is the second choice.
Question 2:
Use the cosine of an angle, which is the adjacent side divided by the hypotenuse.
Multiply 10 by the cosine of 44 degrees to get our answer.
[tex]10 \cos(44)[/tex]
[tex]\approx 7.2[/tex]
Your answer is the first choice. I hope this helps! :)
