ANSWER
C. 58°
EXPLANATION
The sum of the interior angles of a triangle is 180°.
We sum all the three angles to obtain,
.
We group like terms to get,
.
Simplify,
.
Combine like terms to get,
.
Simplify,
.
Divide both sides by 32 to get,
.
We substitute the value of x into the expression for
.
This implies that,
.

The correct answer is C
Let's first find out their factors.
90's factors are :
190's factors are :
The common factors of 90 and 190 are :
1,2,5 and 10.
The greatest one among these is, 10. So the greatest factor of 90 and 190 is 10.
Answer:
y= 2x+1
Step-by-step explanation:
Points:
Form of the line:
- y=mx+b, m- the slope, b- y-intercept
Finding the slope:
- m= (y2-y1)/(x2-x1)
- m=(3-1)/(1-0)= 2/1= 2
Line is now:
Using one of the given points to find out the value of b:
So the equation for the line is:
4x=8
This is because when you add the two expression together 2x+2x=4x the y values cancel and -4+-4=-8
4x-8=0 is equivalent to 4x=8
