Answer:
56.6 °
Step-by-step explanation:
For a RIGHT triangle cos (x ) = adjacent leg / hypotenuse
cos (x) = 4.4 / 8
arc cos (4.4/8) = 56.63 ° = ~ 56.6°
Let area to be painted = X m²
Rate for Allen = X / 16 m² / h
Rate for Brianne = X / 18 m² / h
Combined rate
X/16 + X/18 m² / h
[ 18X + 16X ] / 144 m² / h
34 X / 144 m² / h
time = X / [ 34 X / 144 ] h
time = 144 / 34 h
time = 4 h 14 min
