8 if not that then its 56 or i might be wrong but it seems right to me
The slope is 1/2............
the sum of supplementary angles equals 180°
(4y + 7) + (9y + 4) = 180°
13y + 11 = 180
13y = 169
y = 13
m∠2 = 9y + 4 = 9(13) + 4 = 117 + 4 = 121
Answer: 121°
60 and 72 is 12 GCF
45 and 81 is 9 GCF
You have to find the mean (average) which is (10+x)divided by 2 to get how long it would take them together. (chase is x because you don’t know how long yet so u use a variable)
