<h3>Answer: 35.4</h3>
====================================================
Explanation:
Let x be the reference angle where the question mark is located.
Opposite this angle x is 27. The adjacent side is 38.
Use the tangent ratio to tie the two sides together
tan(angle) = opposite/adjacent
tan(x) = 27/38
x = arctan(27/38)
x = 35.3947958 .... which is approximate
x = 35.4
Be sure that your calculator is in degree mode. The notation "arctan" refers to "arctangent" which is the same as inverse tangent. Your calculator should have a button labeled to help compute this.
Answer:
1. False
2. True
Step-by-step explanation:
1. 3v 60
3(10) 60
30 60
2. x + 18 < 32
2 + 18 < 32
20 < 32
