Question

Just question 1A and 2A with explanation please. Lots of point and brainliest!

Answer 1

Answer:

1a. x + 74.5= 90

subtract both sides by 74.5

x= 15.5° the results

2a. Set up the given

x + 180=180

subtract both sides by 180

x = 0 is the results

Answer 2

1A

1/2 = 0.5

74 & 1/2 = 74 + 1/2 = 74 + 0.5 = 74.5

The complement to this angle is 90 minus the angle, so,

complement = 90 - angle

complement = 90 - 74.5

complement = 15.5

Convert this to a mixed number

15.5 = 15 + 0.5 = 15 + 1/2 = 15 & 1/2

If the given angle is 74 & 1/2 degrees, then the complement is 15 & 1/2 degrees

Answer: 15 & 1/2 degrees

==========================================

2A

180 is the given angle. The supplement, let's call it x, will add to the given angle to get 180.

x+180 = 180

x+180-180 = 180-180

x = 0

So if we add 0 to the given angle 180, we get the result 180

Answer: 0 degrees
