Step-by-step explanation:

y = 15× tan25° = 15×0.466 = 6.99 m

r (Hypotenuse) = 15/cos25° = 15/0.906

= 16.56m

the total height = 6.99+16.56 = 23.55 m

Ten times the square of a non-zero number is equal to fifty times the number. what is the number?

10x^2 = 50x.....subtract 50x from both sides
10x^2 - 50x = 0...factor
10x(x - 5) = 0

10x = 0
x = 0 <== this one is eliminated because x cannot be zero

x - 5 = 0
x = 5 <== ur answer

Greetings!

Substitute:
$x+y=1000 \\ x=1000-y$
Now we can input this into the other equation so, we only have one variable.

Solve for y.
$0.05(1000-y)+0.06y=57$
Distribute the parenthesis.
$50-0.05y+0.06y=57$
Combine Like Terms.
$50-0.01y=57$
Add -50 to both sides.
$(50-0.01y)+(-50)=(57)+(-50)$
Simplify.
$0.01y=7$
Divide both sides by 0.01.
$(0.01y)/0.01=(7)/0.01$
Simplify.
$y=700$

Input this value into the other equation.
$x+700=1000$
Add -700 to both sides.
$(x+700)+(-700)=(1000)+(-700)$
Simplify.
$x=300$

The answer would be 300,700

Hope this helps.
