Question

a pair of supplementary angles are in the ratio of 3: 7 find measure of them​

Answer 1

Question:
A pair of supplementary angles are in the ratio of 3: 7 find measure of the angles.

Solution:
Let the angles be 3x & 7x.
(Two angles are supplementary when their sum = 180)
3x + 7x = 180
10x = 180
x = 180/10
x = 18

The two angles are :
3x = 3*18 = 54
7x = 7*18 = 126

Answer 2

Answer:

The two angles are:

3x = 3×18 = 54

7x = 7×18 = 126

Step-by-step explanation:

Let the angles be 3x & 7x. (Two angles are supplementary when

their sum = 180)

3x + 7x = 180 10x = 180

x = 180/10

x = 18

The two angles are:

3x = 3×18 = 54

7x = 7×18 = 126
