Answer:
h = 18( I might be wrong though)
Step-by-step explanation:
If BE and ED are perpendicular, that means this angle is supplementary.
BEF = 3h-12
FED = 2h - 23
BEF + FED = 90
3h-12 + 2h - 23 = 90
5h - 35 = 90
5h = 90
h = 18 degrees
Answer:
Both triangles have acute angles
In 20 minutes John can rap 10 small boxes and Hank can rap 12 small boxes
A=8,502×(1−0.13)^(16)
A=915.86
