Since they are vertical angles, they equal each other. Therefor the equation would be: 30x-29 = 20x+21
10x = 50
X = 5
After, you plug whatever x is back into the other equations.
20(5)+21 = 121 and 30(5)-29 = 121
Please note that in proving this, I have used trigonometric identities other than just the sine angle-addition formula.
the answers are 9,000 and 900
