Solving Trigonometric Equations

Solve each equation for exact solutioons in the interval [0, 360]. Use either an algebraic method or a graphical method. 2 sin x -1 = csc x I am hoping that I can have help learning how to solve this problem. I have attempted many times, but I have consistently failed in figuring out how to solve it and other problems like it. Please help me!

Sum Identity for Tangent

Find the exact value of the expression using the provided information. Find tan (B + C) given that sin C = 1/4, with C in quadrant II, and sin B = -1/2, with B in quadrant IV. Please help! I've made many attempts at this problem and it seems as though I'm always doing something wrong, but I can't figure out what.

Double Angle Identities and Solving Trigonometric Equations

I need help solving Double Angle Identities: Find the exact value, given that sin A = -4/5 with a in quadrant IV. cos 2A I also need help Solving Trigonometric Equations: Solve each equation for solutions in the interval [0, 360). Use either an algebraic method or a graphical method. tan x - cot x = 0 csc^2 x - 2 cot x = 0 Please help! I am stuck! Thank you!

Height question

While traveling across flat land, you notice a mountain directly in front of you. The angle of elevation to the peak is 2.5 degrees. After you drive 17 miles closer to the mountain, the angle of elevation is 9 degrees. Approximate the height of the mountain. (show all you work, including graphs)
