Question

two angles of quadrilaterals are measured 75 degree and 117 degree respectively at other two angles are equal find the measure each of the equal angles

Answer 1

two angles are respectively 75° and 117°.
quadrilaterals are sum is 360°.
Angles 1 +2 + 3 + 4 = 360°
75° + 117° + 3 + 4 = 360°
192° + 3 + 3 = 360°
2[3] = 360° - 192
2[3] = 168°
2[3] = 168°/2
2[3] = 84°

Answer 2

Answer:

Step-by-step explanation:

two angles are respectively 75° and 117°.

quadrilaterals are sum is 360°.

Angles 1 +2 + 3 + 4 = 360°

75° + 117° + 3 + 4 = 360°

192° + 3 + 3 = 360°

2[3] = 360° - 192

2[3] = 168°

2[3] = 168°/2

2[3] = 84°
