Question

two angles are supplementary in the ratio 1:3 .find an​

Answer 1

Step-by-step explanation:

angles are x and 3x

x + 3x = 180

4x = 180

x = 180/4

x = 45

two angles x = 45 and 3x = 45 × 3 = 135

Answer 2

Step-by-step explanation:

Let the angle be:-

$x \: and \: 3x \\ = x + 3x = 180 \\ = 4x = 180 \\ = x = \frac{180}{4} \\ = x = 45 \:$

first angle

x=45 and second angle is 3x = 3×45= 135
