Question

1. Given △PQR≅△STU, m∠R=80°, and m∠S=70°, what is the measure of ∠Q?

Answer 1

1) Since â–łPQR is a triangle, all angles must add up to 180°. 180 - 80 - 70 = â Q â Q = 30° 2) (5x - 10) = (3x + 40) Combining terms, 2x = 50 so, x = 25 mâ AEB = (5x - 10) mâ AEB = 115°

Answer 2

1) i'm actually trying to find the answer to that same question 

2) All vertical angles add up to 360 so 360/2= 180 so <AEB is 180
