and \text{m}\angle V = 71^{\circ}.m∠V=71

. Find \text{m}\angle U.m∠U.


Answer :

Answer:

m∠U = 54.5°

Step-by-step explanation:

ΔUVW is an isosceles triangle.  The angles opposite UV and VW are congruent.

That means m∠U = m∠W

Since the measures of the angles of a triangle have a sum of 180, then

m∠U + m∠W + m∠V = 180

m∠U + m∠U + 71 = 180

2 m∠U = 109

m∠U = 54.5°
