Answer:
Option B.
Step-by-step explanation:
We need to find the circle that has a central angle that measures 40°.
In all options, the center of circle is U. It means central angle must be on center, i.e., U.
In option A,the angle VXZ is at point X which is not the center. So, angle VXZ is not a central angle.
In option B,the angle VUZ is at point U which is the center. So, angle VUZ is a central angle with measure 40°.
In option C,the angle XZV is at point Z which is not the center. So, angle XZV is not a central angle.
In option D,the angle VXZ is at point X which is not the center. So, angle VXZ is not a central angle.
Therefore, the correct option is B.
Answer:
A. tossing five coins
C. spinning a spinner with 2 equal parts 5 times
Step-by-step explanation:
There are two equally likely outcomes for each kitten's gender: male or female.
A coin has two equally likely outcomes: heads or tails. So tossing five coins can be used to simulate the probability.
A spinner with two equal parts also has two equally likely outcomes. So spinning a spinner with two equal parts five times could also be used to simulate the probability.

V=πr²h
V=π(1.8/2)²(3.5ft)=.9639ft³×1min/2.3ft³=.419 min
Answer: X=19
Step-by-step explanation:
Add up everything and set it to 180 degrees so (5x+4)+(x-2)+(3x+7)=180
next 9x+9=180
then 9x=171
x=19
If you want to check by pluggin in value for x for all angles and it should equal 180 added up
Angle POS= 99
Angle SOR= 17
Angle ROQ= 64
99+17+64=180 degrees
Answer:
B. 720°
Step-by-step explanation:
We are given;
A six sided polygon
We are required to determine the sum of interior angles;
We need to use the formula;
Sum of interior angles = (n-2) 180
Where, n is the number of sides of the polygon
In thus case, n = 6
Therefore;
sum of interior angles = (6-2) 180
= 720°
Thus, the sum of interior angles of the polygon given is 720°
