Question

if the ratio of two adjacent angle of a parallelogram is 5:7 find the angles of parallelogram​

Answer 1

Answer:

Let the ratio be 5x : 7x

We know that the sum of adjacent angle of a parallelogram is 180°

A/q

5x + 7x = 180

=> 12x = 180°

=> x = 180/12

=> x = 15

Hence , the two adjacent angle is

5x = 5×15 = 75°

7x = 7×15 = 105° Ans...

Answer 2

Answer:

we know the adjacent angles of a parallelogram are supplementary hence we have to work accordingly

let's bring ratio in terms of x

5x+7x=180

12x=180

x=15

5x=75

7x=105

and other two angles are 75 and 105 respectively

please give me the brainliest answer.
