C=15 is the correct answer.
Answer:
x=6
Step-by-step explanation:
/AB/=2x+12
/BC/=5x+10
3x+2=5x-10 subtract 2 from both sides
3x=5x-12 subtract 5x from both sides
-2x=-12 divide both sides by -2x
x =6
Answer:

Step-by-step explanation:
The equation is in slope-intercept form so y = mx + b, so whatever number is in front of the x (called a coefficient) is your slope, in this case 3/4
Out of the three options the first one is the right answer with the given numbers <span />
Two sides are equal in an isosceles triangle. This means that the angle both sides make with the third side must be the same. Since the angles in a triangle add up to 180°, you can subtract 110° from 180° and divide your answer by two. The resulting number will be the measure of each of the two unknown angles
