Question

Two adjacent angles of a parallelogram are in the ratio 4:5. What is the largest angle

Answer 1

Answer:

the largest angle is equal to 100 degrees

Answer 2

Answer:

measure of largest angle is 100 degree

Step-by-step explanation:

Let the common multiple be ' x '

thus 4x and 5x are measure of adjacent angle

4x +5x = 180. ...... sum of adjacent angle of a parallelogram is 180

9x=180

X = 180/9

X = 20

1st angle is 4x

thus 4×20= 80

and 2nd angle is 5x

thus 5× 20 = 100

100 is greater than 80 hence largest angle is 100 degree
