Question

An angle measures  25° . What is the measure of its supplement? (b) An angle measures  30° . What is the measure of its complement?​

Answer 1

Answer:

supplement angle of 25° = 155°

complement angle of 30° = 60°

Step-by-step explanation:

supplementary angles add up to make a sum of 180°

i.e.

25 + x = 180

x = 180 - 25 = 155

thus,

supplement angle of 25° = 155°

complementary angles add up to make a sum of 90°

i.e.

30° + x = 90°

x = 90 - 30 = 60°

thus,

complement angle of 30° = 60°
