Question

∆GHI is an isosceles triangle with a vertex angle H If the m∠H=80°, then find the m∠I.

Answer 1

d is the answer on edge 2022

Explanation:

Answer 2

m∠I = 50 degrees

Explanation:

Mathematically, the base angles of an isosceles triangle are equal

So in this case, since H is a vertex;

m∠I + m∠H + m∠G = 180

m∠I = m∠G = x

2x + 80 = 180

2x = 180-80

2x = 100

x = 100/2

x = 50
