Answer:
55m
Step-by-step explanation:
a²+b²=c²
19 x 19 = 361
52 x 52 = 2704
2704 + 361= 3065
the square root of 3065 is 55.4 so round that to 55.
To find the x value of the vertex we do:
x =

if your quadratic function is in the form ax² + bx + c = y
x =

x =

Now we plug this x into the equation and solve for y.
y =

y =

y =

y =

y =

y =

Your vertex (if my math is correct) is at
Answer:
34
Step-by-step explanation:
Add them together
5x+10=180
5x+10-10=180-10
5x=170
5x/5=170/5
x=34
Answer:
<u>C</u>: <em>3x + 80 + 2x = 180</em>
Step-by-step explanation:
A straight line is equal to 180 degrees total the find x, you would add the number within the line and make it equal to 180.
3x + 80 + 2x = 180
add like terms
5x + 80 = 180
subtract 80 from each side
5x = 100
divide each side by 5
x = 20
