Answer:
90°
Step-by-step explanation:
Let there measures of the angles of a triangle are 2x, 2x and 4x.
We know that the sum of angles of a triangle is equal to 180°. So,
2x+2x+4x=180
8x=180
x = 22.5
We know that, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
So, the exterior angle = 4x = 4(22.5) = 90°
