-14 because it's 4-15+ (-3)
A is a chord.
B is a diameter.
C is a circle
D Is a radius.
Now you have the answer to four questions!
Answer:
Both are 117 degrees.
Step-by-step explanation:
Since 6 and 8 are vertical angles, they are congruent. So, 8 is also 63 degrees. Angle 4 corresponds to angle 8, so it is also 63. Angle 2 and angle 4 are vertical, so they are also congruent. So, angle 2 is 63. Since angle 1 and 2 form a straight line (180 degrees), you can find angle 1 by subtracting 63 from 180. You get 117. And since 1 and 3 are vertical, 3 is also 117.
Answer:
I do not know, but I do know the formula.
The formula is: 12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
