Answer:
The answer is D on edgen.
Step-by-step explanation:
D. 80
(all you do is add 40, 14 and 26 from the graph)
The supplementary angle would be 180 degrees, and the other angle would be 92.2 degrees
Let S be the first side.
Longest side is then 2S.
Third side is 2S-10.
Perimeter is sum of all three sides = S+2S+2S-10 = 75
=>
5S-10=75
5S=75+10=85
S=17
Therefore
S=17 is the first side.
Longest side is then 2S=2*17=34.
Third side is 2S-10=2*17-10=24.
It’s 0.498 just divide -2.49 and -5
