V. In a parallelogram ABCD, ∠A = ( 6 X – 17 )° and ∠C = ( X + 63 )°, then ∠B = …….. |
|
Answer» We have, In PARALLELOGRAM ABCD ∠A=(6x−17) o and∠C=(x+63) o
Find the VALUE of ∠A
Then, We know that ∠A=∠C ∴It is aparallelogram 6x−17=x+63 6x−x=63+17 5x=80 x=16 o
Then, ∠A=6x−17 ∠A=6×16−17 ∠A=96−17 ∠A=79 o
Hence, this is the answer. |
