Answer:
∠J = 60°
Step-by-step explanation:
The Law of Cosines tells you ...
j² = k² +l² -2kl·cos(J)
Solving for J gives ...
J = arccos((k² +l² -j²)/(2kl))
J = arccos((14² +80² -74²)/(2·14·80)) = arccos(1120/2240) = arccos(1/2)
J = 60°

It is pretty rare to find a set of integer side lengths that result in one of the angles of the triangle being a rational number of degrees.
Answer:
735N
Step-by-step explanation:
According to Newton's second law;
Force = mass * acceleration due to gravity
'
Given
Mass = 75kg
Acceleration = 9.8m/s^2
Substitute into the formula;
F = 75 * 9.8
F = 735N
Hence the force required is 735N
The ways that Robert could have scored 12 points will be:
- 4 3 points shot.
- 6 2 points shot.
- 12 1 pony shot
<h3>How to express the information?</h3>
From the information, Robert and Frank were shooting baskets. They scored 3 points for a long shot, 2 points for a regular basket, and 1 point for a free throw.
Therefore, to get 12 points will be:
= 4 × 3 points = 12
= 6 × 2 points = 12
= 1 × 12 = 12
