Answer:
P ≈ 48.89°(nearest hundredth)
Step-by-step explanation:
The triangle PQR forms a right angle triangle since angle R is 90°. The triangle has an hypotenuse , adjacent and opposite side.
Using the SOHCAHTOA principle one can find the sine ratio of angle P. Let us designate where each side represent.
opposite side(QR) = 55
adjacent side(PR) = 48
hypotenuse(PQ) = 73
sin P = opposite/hypotenuse
sin P = 55/73
P = sin⁻¹ 55/73
P = sin⁻¹ 0.75342465753
P = 48.8879095605
P ≈ 48.89°(nearest hundredth)
The answer to number 23 is D, 49.
Answer:
6 vans and 6 buses
Step-by-step explanation:
v+b=12 this equation represents the amount of vehicles
6v + 55b = 366 this equation represents the amount of students per vehicle.
after solving you get v=6 and b=6
Answer:
12 meters
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.
84=7h
We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.
84/7=7h/7
12=h
So, the height is 12 meters
