Question

two angles of quadrilaterals are measured 75 degree and 117 degree respectively at other two angles are equal find the fourth angle
​

Answer 1

Answer:

The 4th angle is 84°.

Step-by-step explanation:

Let ∠1 = 75°

∠2 = 117°

∠3 = ∠4 = x

Angles of a quadrilateral = 360°

             ∠1 +∠2 +∠3 + ∠4 = 360°

                75 + 117 + x + x = 360

                                    2x = 360 - 192

                                      x = 168/2

                                      x = 84°

∠3 = ∠4 = 84°

Answer 2

Step-by-step explanation:

two angles are respectively 75degree and 117 degree

sum is 360degree

Angle 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)=84degree
