88 degrees is the answer. You would start by setting up the equation as (5x+7)+(8x+8)+(3x+5)=180 because all angles of a triangle have a sum of 180 degrees. From there you combine like terms which would leave the answer of being 16x+20=180 then you subtract the 20 from 180 to get x by itself. Then that would leave you with 16x=160 then you divide both sides by 16 to get x=10. From there you plug 16 into the x in the planetarium equation which is 8(10)+8 which equals 88 degrees

Step-by-step explanation:
Answer:
-22
Steps:
Substitute 3 in for x in f(x);
f(3) = 3 - 1
f(3) = 2
Substitute 3 in for x in g(x);
g(3) = 3^2 - 5 * 3
g(3) = 9 - 15
g(3) = -6
Then multiply this by 4;
4g(3) = 4 * -6
4g(3) = -24
Then add these together;
2 + (-24) = -22
Answer:
18.285 in.²
Step-by-step explanation:
3 in. × 4 in. = 12 in.²
A = πr²
A = 12.57 in.²
12.57 in.² ÷ 2 = 6.285 in.²
6.285 in.² + 12 in.²
18.285 in.²
