Question

Please helppp !

whats the measure of angle 1

Answer 1

answer:70
explanation: because all three angles have to add up to 180 and since they gave us 40 we can easily take 40 from 180. 180-40=140 and now we have 140 left and since there’s two angle left you divide by 2, 140/2 and we would get 70

Answer 2

1 = 70

Explanation:

The triangle is an isosceles.

Subtract the angle 40 from 180 (all angles in a triangle add up to 180

The bottom two angles are the same, so dividing the number given by 180 - 40 by 2

180 - 40 = 140

140 / 2 = 70
