Answer: <1=115°, <2=115°, <3=65°

Explanation:

Since one of the properties of isoceles trapezoids are the fact that they have congruent lower base angles, we can assume that <3=65°. Since each quadrilateral contains angles that add up to 360°, Since we have 2 angles that are both 65°, we can add them together, which results in 130°, and subtract from 360°, which results in 230°. Since isoceles trapezoids have equal upper base angles, we can divide this by 2, which results in angles <1 and <2 being 115°.

Answer:

1 = 115°

2 = 115°

3 = 65°

Explanation:

P=65, so S (3) =65

360-65-65=230

230/2=115

Q (1) = 115

R (2) = 115
