Answer:

C = 21°
a = 13.3
c = 5.4

Step-by-step explanation:

The third angle can be found from the sum of angles in a triangle.

A + B + C = 180°

C = 180° -62° -97°

C = 21°

The remaining side lengths can be found using the Law of Sines.

a/sin(A) = b/sin(B)

a = sin(62°)(15/sin(97°)) ≈ 13.34

Similarly, ...

c/sin(C) = b/sin(B)

c = sin(21°)(15/sin(97°)) ≈ 5.42

The remaining side lengths are approximately ...

a ≈ 13.3

c ≈ 5.4

Answer:

0.2839 = 28.93%

Step-by-step explanation:

In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z

Le x be tons of coal in a car

Z = (x – mean)/standard deviation

Z = (x – μ)/ σ

P (x<68.5) = P(z < (68.5-69)/0.9)

P (x<68.5) = P(z < -0.5555)

Then we use the z table to find the area under the curve.

P (x<68.5) = 0.2893
