Question

ABCD is a parallelogram in which ∠ = 70௢

. Compute ∠B, ∠C, and ∠D​

Answer 1

Step-by-step explanation:

opposite angles in a parallelogram are equal

then <A = <C

<B = < D

if angle <A = 70 then <C = 70

then take <B=<D= x

sum of angles in a parallelogram = 360

<A+ <B+<C+<D = 360

70 + x+ 70 + x = 360

2x + 140 = 360

2x = 360 - 140

2x = 220

x = 220/2 = 110

Therefore <B and <d = 110
