Question

the measure of two digit number
adjacent angle of a
measure of
each vide
the parallel
ratio
3: 7
angle of the
gram in the
parallelogram in the aute ratio​

Answer 1

Answer:

Let two adjacent angles A and B of ∥gm ABCD be 3x and 7x respectively.

Since the adjacent angles of a parallelogram are supplementary.

∠A+∠B=180°

⇒3x+7x=180°

⇒10x=180°

⇒x=10/180

x=18°

∴∠3×18 °

=54°

and, ∠B=2×18°

=36°

Since the opposite angles are equal in a parallelgram, therefore, ∠C=∠A=54°

and ∠D=∠B=36°

Hence, ∠A=54°

,∠B=36°

,∠C=54°

and ∠D=36°
