In ∆ABC, AC = 15 centimeters, m B = 68°, and m C = 24°. What is BC to two decimal places?
Answer provided by our tutors
we are given two angles and one side (which is not between the angles)
we find the angle m A by using 'angles of a triangle add to 180°':
m A = 180 - (m B + m C)
m A = 88°
we can find side BC by using The Law of Sines:
BC/sin A = AC/sin B
BC/sin 88° = 15/ sin 68°
BC = 15*sin 88° / sin 68°
BC = 16.19 cm.
Answer:
252pi (B)
Step-by-step explanation:
Find the area of the bases (2 * pi * r^2)
r = 6, so:
72pi = total area of bases
Find the area of the side (pi * 2 * r * h)
r = 6 and 15 = h, so:
180 pi = area of the side
180pi + 72pi = 252pi (B)
will she would have rode 4 3/5 miles in all.
2 3/10+2 3/10=4 3/5
that is 2 3/10 there and 2 3/10 back so you would add that together.
MILES IN ALL 4 3/5
Hope this helps
Answer:
The magnitude of the resultant force is:
The direction is:
Step-by-step explanation:
Let's find the components of each vector is x and y-directions first.
<u>Sum of x-component vector forces.</u>
<u>Sum of y-component vector forces.</u>
The magnitude of the resultant force is:
The direction is:
