The angle of elevation from a soccer ball on the ground to the top of the goal is 34. If the goal is 8 ft tall, what is the dist
Nastasia [14]
You can use the Pythagorean Theorem. Which is a^2 + b^2 = c^2.

So now to plug in the equation.

In your case a is 8 and c is 34. So now we need to solve for b.


8 squared is equal to 64.
34 squared is equal to 1156.

Now to plug things in.

64 + b^2 = 1156

Now subtract 64 from 1156.

That equals 1092.
The equation is now

b^2 = 1092

Now do the square root of 1092.

But since the square root is an irrational number you can just write b = 1092 ( but put a square root with 1092)

Can anyone help with this??
Kipish [7]

Answer:

y=x+6

Step-by-step explanation:

the co-ordinate points are (-2,4)and (4,10) so <u>y2-y1 </u>

                                                                           x2-x1    

<u>10-4 </u> =6

4-2    =6   which will be 1 as the gradient so you will form an equation

<u>y-10</u> =1 cross multiply the values with one so the answer will be y-10=x-4

x-4  

take -10 to the other side it will be y=x-4+10 hence y= x+6
