The central angle COA = 2 * angle at the circumference
m < COA = 2 * 80 degrees
Answer:
The answer is C, i got it wrong on USAtestprep so i can answer it for you :)
Step-by-step explanation:
To get the multiplicative inverse of any number, just take the reciprocal of that number.
So for 1/4, it is 4/1
= 4/1 = 4
Multiplicative inverse of 1/4 is 4.
To find the surface area of the entire sculpture, you need to add up the surface area of each part of the sculpture. Overall, you see two triangles connected by two rectangles at the top, and the half of a cylinder at the bottom.
To find the area of one of the two triangles, you use the equation A = (1/2)bh, where b = the base of the triangle and h = the height. So, the area of one triangle is:
60:45, 60 to 45, and 60/45
If it needs to be simplified, replace 60 with a 4 and 45 with a 3 (ex. 4:3)
