Answer:

A. Isosceles

Step-by-step explanation:

Since two angles are congruent, then the opposite sides are congruent. The two congruent angles measure 70 and 70.

70 + 70 = 140

180 - 140 = 40

The third angle measures 40. The third side is not congruent to the other two, so the triangle is isosceles but not equilateral.

This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!

How can I find the volume of a cone 9 radius and 18 height

Anastasy [175]

Answer:

V = 486 $\pi$ , or approx. 1,526.814

Step-by-step explanation:

V = $\pi$ *r²*(h/3)

plug in the numbers: V = $\pi$ * (9)² * (18/3)

simplify: V = $\pi$ * 81 * 6

simplify: V = 486 $\pi$ , or approx. 1,526.814

What is f–1(8)??<br><br> Please select the best answer

notka56 [123]

Answer:

$f^{-1}(8)=\frac{3}{2}$

Step-by-step explanation:

Given f(x)= $2x+5$

We have to find $f^{-1}(8)$

In order to find $f^{-1}(x)$ we have to make x as the subject of the formula

Let us assume f(x)=y

⇒ $2x+5=y$

Subtracting both sides by 5

$2x+5-5=y-5$

$2x=y-5$

Dividing both sides by 2

$\frac{2x}{2}=\frac{y-5}{2}$

⇒ $x=\frac{y-5}{2}$

Now substituting y with x

we have $f^{-1}(x)=\frac{x-5}{2}$

Now $f^{-1}(8)=\frac{8-5}{2}$

= $\frac{3}{2}$

So option (ii) is correct

The rectangular rug has side lengths of 3 and 4 ft. What is the length of the diagonal? Draw a picture of the problem and solve.

Nadusha1986 [10]

ANSWER

The length of the diagonal is 5 ft

EXPLANATION

The diagram of the rug with the diagonal is:

The diagonal and the sides form a right triangle, so we can use the Pythagorean theorem to find x, the length of the diagonal:

$\begin{gathered} x^2=3^2+4^2 \\ x=\sqrt[]{9+16} \\ x=\sqrt[]{25} \\ x=5 \end{gathered}$
