Question

The measure of an angle is 2° less than thrice its complementary angle. What is the measure of that angle? (1) 67° (2) 23° (3) 76º (4) 32°​

Answer 1

Answer:

(1) 67°

Step-by-step explanation:

Let x and y are complementary angles.

It means x+y=90.

And X=3y-2 given putting in above eq we get

3y-2+y=90

4y-2=90

4y=92

Y=23

X=90–23=67.
