Difference between two complementary angles
is 60°. Find each angle.
Answers
What is complementary angles ?
Complimentary angles are pair of those angles whose sum makes an angle of 90°.
Now ,taking various cases to find out the angle measure.
Given that the difference of two complementary angles is 60°
Let us assume that the first angle be x
second angle be y
According to the Question
x-y=60°
Taking possible cases
90°30°=60° case I
Here ,it is not possible because 90+30=120>90° which not formed a complimentary angle.
Taking 2nd situation
80-°20°=60° Case II
Here,it's not possible because 80°+20°=100° which is >90° not a complimentary angle.
70-10°=60° Case III
It is possible because 70+10=80° which is <90° it's also not a complimentary angle
Case IV
75°-15°= 60°
Here,it's a complimentary angles pair
as 75°+15°=90°
∴The angles are 75° & 15°
Alternative method
Let the first angle be 'x'
second angle be 90-x
90-x-x=60°
90-2x=60
-2x=-30
x=15
second angle =90-15=75°
∴The angles are 15° & 75°
