Question

Adjacent angles of parallelogram are 5:4. Find the measure of each angle.

Answer 1

Answer:

Given ratio 5:4

Step-by-step explanation:

let the one adjacent angle of llgm be 5x and other 4x.

5x+4x=180⁰ (Adjacent angle of parallelogram are supplementary)

9X=180⁰

X= 180⁰ ÷9

X= 20⁰

thus, 5x=5 multiply 20 degree

= 100 degree

4x= 4 multiply 20 degree

= 80⁰
