Since a triangle's angles add to be 180 degrees, you need to find the measure of the third angle.
180-55-65= 60 degrees

The equation would be 2x+30=60
2x=30
x=15
Answer:
Step-by-step explanation:
- -2x + 6 = -20
- -2x = -20 - 6
- -2x = -26
- x = -26 / -2
- x = 13
Answer:
B) 113.1 cm³
Step-by-step explanation:
The cross-section of a sphere is a circle. The area of a circle is:
A = πr²
The largest cross section passes through the center of the sphere, where the radius of the circle equals the radius of the sphere.
28.27 = πr²
r = 3.00
The volume of the sphere is therefore:
V = 4/3 π r³
V = 4/3 π (3.00)³
V = 113.1
Answer:
Slope- 5 y-int- (0,0)
Step-by-step explanation:
y=mx+b, where m=slope and b=y-int. m=5, and we don't see a b, so it must be 0.
