Answer:

Step-by-step explanation:

1.From the given triangle, ABC, using the proportionality theorem, we get

$\frac{FA}{CA}=\frac{EF}{BC}$

⇒ $\frac{8}{40}=\frac{5}{x}$

⇒ $x=25ft$

Thus, the height will be 25 feet.

Statement Reason

1.∠C≅∠E Given

2. ∠ABC≅∠DBE Vertically opposite angles

3. ΔABC is similar to ΔDBE AA similarity rule.

The hypotenuse of a right triangle is three times the length of one of its legs. The length of the other leg is four feet. Find

andre [41]

Hello!

It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.

$a^2+b^2=c^2$

We can set the length of a leg as an unknown variable $x$ .

$x^2+4^2=(3x)^2$

Remember that it is the whole $3x$ term being squared, meaning that it'll simplify to $9x^2$ , not $3x^2$ .

$x^2+16=9x^2$

$8x^2=16$

$x^2=2$

$x=\sqrt{2}$

This means we can plug back in to find the sides.

The hypotenuse would be $3\sqrt{2}$ , or 4.2.

And the legs would be 1.4 and 4, respectively.

Hope this helps!
