Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
Answer:
Correct answer is option D. 96.4 yd.
Step-by-step explanation:
Please refer to the attached figure for labeling of the given diagram.
ABC is a triangle with the following labeling:
A is the hole, B is the Tee and C is the point where the ball is.
Sides are labeled as:

To find:
Side 
Solution:
Here, we have one angle and two sides . Third side of the triangle is to be found opposite to the given angle.
We can use cosine formula here to find the value of the unknown side.

Putting all the values:

So, the distance between the Ball and hole is 96.42 yd
Correct answer is option D. 96.4 yd.
Answer:
<h3>
The cylinder's radius is <u> 2 </u> inches </h3><h3>
and it’s height is <u> 3 </u> inches.</h3>
Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in
First multiply 180 and 25 which is 4500.
Then divide by 17 which should be approximately 264.71
