Answer:
X = 45
Step-by-step explanation:
90+45+X=180
135 + X = 180
X = 180 - 135
X = 45
hope it helps!
Right away we know we don't have fractions; the midpoint is the average of the coordinates, so if it and one endpoint are integers so is the other endpoint.
We can do a kind of point arithmetic:
C = (A+B)/2
2C = A+B
B = 2C - A
B = 2(6,1) - (1,3) = (12,2)-(1,3)=(11,-1)
Answer: That's none of the above, but a typo away from the first choice.
<span>1. A = 1/4s squared, square root of 3 equilateral triangle
2. A = bh rectangle
3. A = pi(r) squared circle area
4. A = 1/2 h (b1+ b2) trapezoid
5. C = pi(d) circle circumference
6. A = base x altitude parallelogram
7. A = 1/2(ap) regular polygon
8. A = 1/2(bh) triangle
</span><span>- regular polygon
- trapezoid
- parallelogram
- circle circumference
- equilateral triangle
- circle area</span>
Answer:
A = -12
B = -8
C = -4
Step-by-step explanation:
x = -2
A = -12
x = 0
B = -8
x = 2
C = -4
Hope this helps
