Question

An angle of a parallelogram measures 70°. Find the measure of the remaining three angles.

Answer 1

Answer:

Step-by-step explanation:

Parallelogram has 4 angle

Angle a,angle b,angle c,angle d

Angle a =angle c ,angle b =angle d

Let us suppose angle a =70

Therefore angle c=70

Angle a +angle c= 70+70=140

360-140=220

Therefore angle b +angle d= 220

Angle b = angle d

Therefore 2×angle b =220

Angle b =110

Angle b =angle d= 110

Answer 2

Answer:

Step-by-step explanation:

Parallelogram has 4 angle

Angle a,angle b,angle c,angle d

Angle a =angle c ,angle b =angle d

Let us suppose angle a =70

Therefore angle c=70

Angle a +angle c= 70+70=140

360-140=220

Therefore angle b +angle d= 220

Angle b = angle d

Therefore 2×angle b =220

Angle b =110

Angle b =angle d= 110
