Answer:
Step-by-step explanation:
It’s 180°. The sum of the angles in a triangle is ALWAYS 180°.
To solve these problems you need to use the quadratic formula which is listed below.

So, if you take #2.
The

has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:
a = 1
b = -3
c = -3
Then you can plug all of these into the equation and simplify. Which gives you:
Answer:
8

-5(a+3)=- 55
-5a-15=- 55
-5a= -55+15
-5a= -40
-5a/-5 =-40/-5
a=8
Answer:
254.57 in^3
Step-by-step explanation:
A cylinder has a height of 9 inches. The radius of the cylinder is 1 / 3 the height of the cylinder. What is the approximate volume of the cylinder?
volume of a cylinder = nr^2h
n = 22/7
r = radius
radius = 9 x 1/3 = 3 inches
(22/7) x (3^2) x 9 = 254.57 in^3
