Answer:
50-20 or perimeter-2length
Step-by-step explanation:
15 inches is the width
the base length is 8 units
You can use pythagorean theorem to solve this
m = -6
3m= 5(m + 3)-3
Distribute
3m = 5m +15 -3
Combine like terms
3m = 5m +12
Subtract 5m
3m-5m = 5m+12-5m
-2m = 12
Divide by -2
-2m/-2 = 12/-2
