Answer:
assuming 60 and 63 are the side lengths
87 in is the hypotenuse
Step-by-step explanation:
60^2 + 63^2 = x^2
Answer:
the answer would be false
So: A + C = 180°
X + 20° + 110° = 180°
Then:
X = 50°
Answer:
Step-by-step explanation:
1) Use the given coordinate points to find the slope
m=
m=
2) plug the slope into slope-intercept form
y=x+b
3) choose one point to use to plug into the equation to solve for b
4=(-2)+b
4) solve for b.
b=
5) substitute the value for b into equation from step 2
y=x+
