Answer:
21
Step-by-step explanation:
y+9 = ?
y=12
12+9=21
Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
Answer:
(x - 3/4)^2 + (y - 1/2)^2 = r^2
<em>Brainliest, please!</em>
Step-by-step explanation:
Equation of a circle: (x - h)^2 + (y - k)^2 = r^2
(x - 3/4)^2 + (y - 1/2)^2 = r^2
We do not have enough information to find the radius. Were you given another point that lies on the circle?
