Rate for Sally is 1 room per 8hrs
rate for Steve is 1 room per 7hrs
combined rate:
1/8 + 1/7 = 1/T
7/56 + 8/56 = 1/T
15/56 = 1/T
56/15 = T
3 11/15 = 3 hrs 44 min

Answer:
A. & A.
Step-by-step explanation:
sin(x) = cos(90-x)
sin(30) = cos(90-30) = 60
sin(60) = cos(90-60) = 30
The lines that cross or intersect at 90 degrees are called perpendicular lines. These lines form a right angle
