2x+2x+6x= 180
10x=180
X= 18
Angle C = 36
Answer:
63
Step-by-step explanation:
7/8 x 72 = 63
Answer:
x = 7
Step-by-step explanation:
These 2 angles are alternate exterior angles which means these angles are equal to each other. The equation is:
2x - 3 = x + 4
2x - x = 4 + 3
x = 7
Answer:
y = 5
Step-by-step explanation:
All the sides are equal, so all the angles are equal
The angles of a triangle add to 180
180/3 = 60
Each angle is 60 degrees
8y+20 = 60
Subtract 20 from each side
8y+20-20 = 60-20
8y= 40
Divide by 8
8y/8 = 40/8
y = 5
Answer:
2 is the answer that I would give. The question says <u>distinct</u> solutions does this graph have.
Step-by-step explanation:
You are asked only how many times this crosses the x axis. You are not asked for an exact value. So the thing to do is graph the polynomial.
y = x^3 - 3x^2 + 4
The graph says that x = -1 with a multiplicity of 1
It also says that x=2 is a solution with a multiplicity of 2 (meaning there are 2 roots are the same).
So this polynomial factors into y = (x + 1)(x - 2)(x - 2)
