(a) An angle measures 51°. What is the measure of its complement? (b) An angle measures 113°. What is the measure of its supplement?

Step-by-step explanation:

For a

Let the another angle be x then

x + 51° = 90° {being complementary angles }

x = 90° - 51°

x = 39°

For b

Let the another angle be x then

x + 113° = 180° {being supplementary angles }

x = 180° - 113°

x = 67°

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
