Question

Find the measure of the larger angle.



51°
180°
129°
32°

Answer 1

The answer is 180 because larger angle is the measure of 180

Answer 2

129

Explanation:

for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do

180=x+19+4x+1

step 1 combine like terms

4x+x=5x

19+1=20

now we have

180=20+5x

step 2 subtract each side by 20

20-20 cancels out

180-20=160

now we have

160=5x

step 3 divide each side by 5

5/5 cancels out

160/5 = 32

x=32

now we want to plug in 32 for each expression to find which one is greater

(32)+19=51

4(32)=128

128+1=129

so the answer is 129

hope this helps :D
