3. Let x be the angle which is equal to its
complement and y be the angle which is equal
to its supplement. Then, 2x + 3y is equal to
(a) 135°
(b) 270°
(c) 360°
(d) 180°
with full solution ​

Answer 1

Answer:

(c) 360°

Step-by-step explanation:

x is equal to its complement, then x is 90°/2 which is 45°.

y is equal to its supplement, then y is 180°/2 which is 90°.

Now,

2x+3y

2×45°+3×90°

90°+270°

360°
