The height of the trre will be given by:
tan θ=(opposite)/(adjacent)
θ=52°
Adjacent= distance of the golfer to the tree= 10 ft
opposite = height, h, of the tree
thus
tan 52=h/10
hence solving for h we get:
h=10tan52
h=12.799~12.8 ft
Answer:
172.7 ft²
Step-by-step explanation:
Fencepost = Cylinder
Cylinder surface area : A = 2πrh + 2πr²
Cylinder surface area : A = 2 (3.14 × 0.5ft × 5ft) + 2 (3.14 × 0.5²ft) =
15.7 + 1.57 = 17.27 ft²
17.27 ft² × 10 = 172.7 ft²
Answer:
132.89 miles
Step-by-step explanation:
Let plane A travel at 130 mph and plane B travel at 150 mph.
After 1.5 hours, the total distance traveled by each plane is:

The law of cosines can be used to find the distance (D) between both planes as follows:

They are 132.89 miles apart after 1.5 hours.
Answer and Step-by-step explanation:
Answer is in picture.
We use the cosine trig function (adjacent side over hypotenuse = cos of an angle) to find m.
The angles are split perfectly in half, half of 90, which is 45, so the other angles are 45.
