Question Description

I’m stuck on a Algebra question and need an explanation.

Student has agreed that all tutoring, explanations, and answers provided by the tutor will be used to help in the learning process and in accordance with Studypool's honor code & terms of service.

Final Answer

1. x = 18 cos 60 = 9 , y = 18 sin 60 = 9 Root(3)

2.  y =x cos 30   ( we can find x & y value in numbers if 3rd side is given )

3. y = 3 cot 30 = 3 root (3)

4.  y= 6 sec 30 = 12/root(3)

5.   x = 21 sin60 = 10.5 root(3), y = 21cos60 = 10.5

6.  y = 9.5 cos 30 = 9.5 root(3)/2

7.  side = 18 sin 60 = 9 root(3)
