Question

if two angles of a quadrilateral are 76 and 138 degree and other two angles are equal find the measure of equal angles​

Answer 1

Answer:

73°,73°

Step-by-step explanation:

Let the two equal angles be x

Sum of all angle s in a quadrilateral is 360°

76 + 138 + x + x = 360°

214 + 2x = 360°

2x = 146°

x = 73°

Therefore the two angles are 73°,73°
