Question

the measure of two adjacent angle of a rhombus are in the ratio 1:2. find the measure of an angle

Answer 1

let angles are x and 2x

Sum of adjacent angles are 180 degree

x + 2x = 180

3x = 180

x = 180/3 = 60

Hence angles are

x = 60

2x = 2 × 60 = 120

Answer 2

Hii ☺

Here is your solution .....☺

_____________________________

✴ let the ratios be "x"

Therefore, adjacent angles are x and 2x

As RHOBUS is a kind of parallelogram, so the sum of its adjacent angle is equal to 180°

=> According to question..

=> x + 2x = 180°
=> 3x = 180°
=> x = 180°/3
=> x = 60°

Hence, 1st angle = x = 60°
and other angle = 2x = 2× 60° = 120°
