Question

if an angle is half of its complementary angle then find its degree measure​

Answer 1

Answer:

I thought that right answer is 45°

Answer 2

Step-by-step explanation:

Let the complementary angle be x

Let the other angle be x/2

According to the question

x+x/2=180

=> 3x/2= 180

so,x=180×2/3

=120

so,complementary angle = 120

And, other angle = 120/2

= 60 degree

Hope this helps.
