Answer: B) 35 degrees</h3>
Explanation:
Angles 4 and 8 are corresponding angles since they are both in the southwest corner of their respective 4 corner configuration.
Corresponding angles are congruent when we have parallel lines like this.
Set the expressions equal to each other and solve for x
angle 4 = angle 8
x+20 = 2x+5
x-2x = 5-20
-x = -15
x = 15
Use this x value to find the two angles to help confirm we have the correct x value, and to finish up to answer the question.
- angle 4 = x+20 = 15+20 = 35
- angle 8 = 2x+5 = 2(15)+5 = 30+5 = 35
So that's why the answer is B) 35 degrees

Step-by-step explanation:
We are give the following in the question:
We have to find the ration of the length of XY to the length XZ.
This, can be done as:
Thus, the ration XY:XZ is 5:14
To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.
V = 1/3 x pi x r^2 x h
1/3 x 3.14 x 8^2 x 1.95
V = 130.624
The approximate volume of the volcano is 131 cubic kilometers.

Answer:
P(6, 1)
Step-by-step explanation:
Point P is the weighted average of the end point coordinates. The weights are the reverse of the order of the segment lengths:
P = (2A +3B)/(2+3)
P = (2(-3, -2) +3(12, 3))/5 = (-6+36, -4+9)/5
P = (6, 1)
