Answer: Theta = 7/5
Step-by-step explanation:
Use the arc length formula s=r(theta)
Rearrange the formula since you are wanting to solve for theta
so theta = \frac{s}{r}
Plug in
theta = 7/5
Answer:
Theta= 7/5

Below in bold.
x^2 - y^2 = 11
2x^2 + y^2 = 97
From the first equation:
y^2 = x^2 - 11
Substituting in the second equation:
2x^2 + x^2 - 11 = 97
3x^2 = 108
x^2 = 36
x = 6, -6.
Substituting for x in the first equation:
(6)^2 - y^2 = 11
y^2 = 36 - 11 = 25
y = 5, -5.

D. 43 degrees
The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...
75° +62° +x = 180°
137° +x = 180° . . . . . . . . . collect terms
x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation
The third angle measures 43°.
In order: B, A, CB, AB, CD
If you read closely, your answers lie within the question.
B is the center of the base.
A is the vertex of the cone.
CB is the radius of the base.
AB is the height from the vertex to the base.
CD is the diameter of the base.
