Answer:
50°
Explanation:
Hi! Angle 3 and Angle 1 are supplementary pair, which means they equal 180°. We can add these two expressions together to solve for x:
Angle 3 + Angle 1 = 180
(10x) + (2x + 24) = 180
10x + 2x + 24 = 180 combine like terms
12x + 24 = 180 subtract 24
12x = 156 divide by 12
x = 13
Now we'll use x to find Angle 1:
2x + 24
2(13) + 24
26 + 24
50
Angles 1 and 2 are congruent, so if Angle 1 is 50°, Angle 2 is also 50°
