Question

if two adjacent angles of parallelogram are (5x-5)and (10x+35)then the ratio of these angles is​

Answer 1

Answer:

we know that

adjacent angles of a parallelogram are supplementary.

5x-5+10x+35=180

15x+30=180

15(x+2)=180

x+2=12

x=10

5x-5=5(10)-5=45

10x+35=10(10)+35=135

Ratio:

5x-5 = 45 = 1

10x+35 135 3

Answer 2

Answer:

1:3

Step-by-step explanation:

In a parallelogram adjacent angles are supplementary, I.e. 180° and opposite angles are equal

In this question,

(5x-5)+(10x+35)=180

15x+30=180

15x=180-30

15x=150

X=10

5x-5 = 45°

10x+35 = 135°

Ratio=45:135

= 9:27 = 1:3

= 1:3
