The answer is 4.5*5*-2= -45 Thanks!
Angle BOC = 120
PROOF
Angle A + Angle B + Angle C = 180
So, Angle B + Angle C = 120 (Angle A = 60)
Now 1/2 (Angle B + Angle C) = 60
1/2 Angle B + 1/2 Angle C = 60..............i
In triangle BOC
1/2 Angle B + 1/2 Angle C + Angle BOC =180
(BO and CO are angle bisectors)
Or 60 + Angle BOC = 180 (using i)
OR ANGLE BOC = 120
Answer:
3.5 hours*3.25 mph=11.375 miles
11.375 miles/3.45 mi/hr=3.297 hours or 3.30 hours, about 12 minutes faster.
Step-by-step explanation:
First, factor out h so the equation can be h(b+r)=25 then divide by b+r so h= 25/b+r
