Question

in a quadrilateral abcd , angle C=64 angle D=angle C -8degree angle A =5(a+2) degree and Angle B = 2 ( 2a+7) degree calculate angle A

Answer 1

Answer:

angle b=a=12.5;angle .

Step-by-step explanation:

C=64 angle D=angle C =8 degree angle A =5(a+2) degree and

AngleB = 2 ( 2a+7) degree are given .

so we need to find angle A.

as angle C and D are equal so we can say that angle A =Angle B

so we get 5(a+2)=2(2a+7).
