Question

I need help ive been suck on this for so long please help me

Answer 1

a = 50

Explanation:

In an isosceles triangle, two angles are equal. In this triangle, the base angles are equal.

65 + 65 + a = 180

Angles in a triangle add up to 180 degrees.

130 + a = 180

a = 180 - 130

a = 50

Answer 2

m∠a = 50°

Explanation:

Since this is an isosceles triangle, we know that the other unknown angle is also 65°. Since all angles in a triangle add up to 180°,

180 - 65(2) = a

a = 180 - 130

a = 50°
