Find the degree measure of < B.


In Quadrilateral ABCD M Lt A 90 M 2 C 50 And M Lt B M D Find The Degree Measure Of Lt B class=

Sagot :

Answer:

m∠B = 170°

Step-by-step explanation:

Sum of all angles in quadrilateral is 360°:

m∠A + m∠B + m∠C + m∠D = 360°

m∠B = 360° - m∠A - m∠C - m∠D

m∠A = 90°

m∠B = m∠D= 50°

m∠B =  360° - 90° - 50° - 50° = 170°
