Answer:

B = 119°

C = 119°

Step-by-step explanation:

The value of back to back angles are the same when the lines are straight.
Therefor there are two 61° they add together to make 122°
You can then subtract 122 from 360 to get 238.
Then take 238 and divide it by 2, to get your answer which is 119° for both.

Answer:

'b' and 'c' = 119 degrees

Step-by-step explanation:

Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.

B, 190.
First you find the area of the circle (pi times radius squared) however, since you are given diameter, you must find radius by dividing diameter by 2. So, your radius is 9, then you plug it into the formula and you get 254.5. After multiplying this by 0.75 because you only want to find 75 percent of the area, you get the answer of 191m
