If two complementary angles are in the ratio 13:5, then the angles are...
Explanation:
Let the angles be 13x and 5x
As we know that complementry angle is 90 degree.
13x + 5x = 90
18x = 90
x = 90/18
x = 5
Putting x values,
13x = 13 x 5 = 65 degree.
5x = 5 x 5 = 25 degree.

If two complementary angles are in the ratio 13:5, then the angles are...
Solution:
Given, two complementary angles are in the ratio 13:5.
Let the two complementary angles be 13x and 5x.
We know that, sum of two complementary angles = 90°
Therefore, 13x + 5x = 90
18x = 90
x = 5
So, the two complementary angles are:
13x = 13 × 5 = 65
5x = 5 × 5 = 25
Hence, the correct option is D) 65° and 25°.
