I think the answer Is D fame
The last graph because the slope is 40.
Slope equals rise over run
Rise is 4/ Run is 1
4/1=4
Slope (rate of change)=4
10 cancels out so its 5/3 :) Rate Me plz <span />
The given angles are complementary, therefore:
(5r + 5) + (8r -6) = 90°
13r - 1 = 90
13r - 1 + 1 = 90 + 1
13r = 91
13r/13 = 91/13
r = 7
