Answer:
42 degrees
Step-by-step explanation:
Angles in a triangle equal 180
180-(37+90)=53
Angles on a line equal 180
180-53=127
127=3b+1
126=3b
b=42
42 degrees
3 1 10
------ + --------------- = ----------
3x x +4 7x
1 1 10
------ + ------------ = ----------
x x +4 7x
x + 4 + x 10
------------------ = ----------
x(x +4) 7x
2x + 4 10
------------------ = ----------
x(x +4) 7x
7x(2x + 4) = 10x(x+4)
14x^2 + 28x = 10x^2 + 40x
4x^2 - 12x = 0
4x(x - 3) = 0
4x = 0
x = 0
x - 3 = 0
x = 3
answer x = 0 and x = 3
the volume of the cylinder is d)168 units
Do 3 minus 1.9
- To make this easier I would do
3 - 2 = 1
1 + 0.1 = 1.1
