Answer:
An isosceles triangle
Step-by-step explanation:
An isosceles triangle has 3 sides and has two equivalent sides with the same measure
Step-by-step explanation:
angle 5, 3, 7 since they're vertical and alternate interior angles that are all connected to angle 1
Ax^2+bx=c
REMEMBER THIS
ok
first, make sure that a is 1
done
now take 1/2 of b and square it
-18/2=-9, (-9)^2=81
add that to both sides
x²-18x+81=19+81
x²-18x+81=99
factor perfect square
(x-9)²=100
square root both sides
don't forget positive and negative root
x-9=10
x-9=-10
ad 9 to both sides
x=19
x=-1
answer is -1; 19
