both triangles are co friend and 90+70=160 180+160=20
Answer:Accurate
Step-by-step explanation:
Answer:
If you were to use the sine formula you would have to use the cosine formula to get one of the opposite sides and then use the sine formula.
For the area why not use 1/2 * 20 to get the base.
Then the height would be 24 * sin 63 = 21.38
That would give an area of 213.8
Answer:
B. 6 hr. 40 min
Step-by-step explanation:
In the question is it said that a mechanic can install carburetors in
3 cars = 4 hours
How long with it take of install carburetors in 5 cars
We have
3 cars = 4 hours
5 cars = X (unknown so we designated it as X)
We cross multiply
3X = 4× 5
3X = 20
Divide both sides by 3
Hence, we have
3X ÷ 3 = 20÷ 3
X = 6.667 hours
In other to convert 6.667 hours to proper time i.e in hours and minutes ,
We have
1 hour = 60 minutes
0.667 hours = y( unknown so we represent with y)
Cross multiply
y = 60× 0.667 hours
y = 40.02 mins.
Approximately ≈ 40 mins
Therefore we add 6 hours + 40 mins
= 6 hours 40mins
Therefore, will it take the mechanic 6 hours 40 minutes to install carburetors in 5 cars
