The drawing shown contains the intersection of two lines.
The measure of ∠1 =20x+21 and the measure of ∠2 =30x-29.
a.Write an equation to determine the measures of both angles.
b. Determine the measures of both angles. Show your work.
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
