Question

if two adjacent angles of a parallelogram are 5 x minus 10 and 10 x + 25 then the ratio of the angle is?​

Answer 1

Answer:

X=11° , angles are 45° and 135° . Ratio =1:3

Step-by-step explanation:

Sum of adjacent angles =180°

(5x - 10°) + (10x + 25°)= 180°

15x +15° = 180°

15x = 165°

x = 11°

{5x-10°}=5×11-10°

=45°

{10x+25°}=10×11+25°

=135°

Ratio =45:135

=45/135

=1:3

Answer:- 1:3
