Answer:
89 meters
Step-by-step explanation:
We know it's 9 + "the height of the triangle".
Fortunately, the height of the triangle (let's call it y) can be computed from:
y^2 + 18^2 = 82^2 (Pythagoras theorem).
y^2 = 82^2 - 18^2 = 6724 - 324 = 6400
y = 80 (or y = -80 but it doesn't make sense in geometry).
so x = y + 9 = 89;

3 ( x ) + 55 = 85
Answer To Solving Y:
Let's solve your equation step-by-step.
3x + 55 = 85
Step 1: Subtract 55 from both sides.
3x + 55 − 55 = 85 − 55
3x = 30
Step 2: Divide both sides by 3.
3x / 3 = 30 / 3
x = 10

2 ( y ) - 5 = 95
Answer:
Let's solve your equation step-by-step.
2y − 5 = 95
Step 1: Add 5 to both sides.
2y − 5 + 5 = 95 + 5
2y = 100
Step 2: Divide both sides by 2.
2y / 2 = 100 / 2
y = 50

But, the anwer should be 180 degrees
Answer:
x=0 x=3 x=-2
Step-by-step explanation:
p(x)= 3x^3 – 3x^2– 18x
Factor out the greatest common factor, 3x
p(x)= 3x (x^2 – x– 6)
Factor inside the parentheses
What 2 numbers multiplies to -6 and adds to -1
-3*2 = -6
-3+2 = -1
p(x)= 3x (x-3)(x+2)
Setting the function equal to zero to find the zeros
0 = 3x (x-3)(x+2)
Using the zero product property
3x = 0 x-3 =0 x+2 =0
x=0 x=3 x=-2
