Need help fast Geometry

Answer 1

Option D; 29°

Explanation:

ΔAOB is isosceles triangle: so ∠B = ∠A, ∠A = 61, therefore:

∠O = 180 - (61 + 61)

∠O = 58

and ∠C = 58 / 2

∠C = 29

Hope this helps!

Answer 2

D. 29°

Explanation:

Triangle ACB is an isosceles triangle so the two base angles are the same(61° and 61°). A triangle's angles must add up to 180, so take 180-61-61.

180-61-61 = 58

Divide by 2 to find angle ACB:

58/2 = 29
