Answer: 12.
Step-by-step explanation: Use Pythagorean Theorem. We that a = 9, b = ?, and c = 15. Plugging that in gives us 9^2 + b^2 + 15^2. Solving for b gets us b^2 = 144. Taking the square root of both sides gets us b = 12.
Your first equation would be:
65 + 3x - 10 + 2x = 180
Then simplify to get:
5x + 55 = 180
Subtract 55 from each side:
5x = 125
Now divide by 5 to find x:
x = 25
The measure of angle B = 65
The measure of angle C = 50
Hope this helps!! :)

Answer:
point slope form is y-1=-1/2(x+4)
Slope intercept form is y=-1/2x-1
Step-by-step explanation:
Point-slope form is y-y_1=m(x-x_1):
plug in values:
y-1=-0.5(x+4)
