Question

if two angles are complementary angles and one is less then 10 degree than three time the other , find the angles​

Answer 1

Answer:

40 degree

Step-by-step explanation:

Let the angles be a and b.

a + b = 90

We know that a = 3b - 10

=> 3b - 10 + b = 90

=> 4b - 10 = 90

=> 4b = 90 + 10

=> 4b = 100

=> b = 100/4

=> b = 25

If first angle is 25, 90 - 25 = 65

Therefore, the two angles are 25 and 65!
