Question

Find the measure of each numbered angle.

m∠1= ___° , m∠2=___°

Answer 1

17°

Explanation:

from the figure it seems that there are two signs at the unknown angles, from the shape it seems like an isosceles triangle, therefore the two angles at the base are congruent, knowing that the sum of the internal angles in a TRIANGLE is 180° we remove the known angle (146°) from 180 and divide the result by 2 and we find the value of the two unknow congruent angles

(180 - 146) : 2 =

34 : 2 =

17°
