The exterior angles of triangle UVW are X, Y, and, and they are adjacent to ZU, ZV, and ZW, respectively.If m/W is 55°, and m/Y is 87°, what is m/U?OA. 93°OB. 32°OC. 55°OD. 125

Answer :

Given

Find

Measure of angle U

Explanation

angle V = 180 - 87 = 93 (linear angle property)

so , now in triangle UVW , by angle sum property ,

sum of all angles are 180 degree,

therefore ,

angle U = 180 - angle V - angle W

angle U = 180 - 93 - 55 = 32

Final Answer

Hence , the correct option is B
