Answer:
83
Step-by-step explanation:
the angle with 126 is supplementary and all the angles of the triangle are supplementary
180-126 = 54
54 + 43 = 97
180 - 97 = 83
I believe the building is 75.5 meters long
The answer is b I think hope this helps
Answer:
y = (x + 6)² - 1
Step-by-step explanation:
So there are two ways of doing it, completing the square or partial factoring (which is what i prefer and will show)
so we will get x first:
x^2+12x
We are factoring x
x(x+12)
Now you do x=-12/2
x=-6
Now that you have x, you plg that back into the equation to get y
y= -6^2 +12(-6) +35
= 36-36+35
=-1
Put into vertex form
y = (x + 6)² - 1
