Use the Hinge Theorem to compare the measures of AD and BD.<br><br> I need help now!!! Please!!!!

gavmur [86]

Answer:

The length AD is greater than length BD.

Step-by-step explanation:

Hinge theorem states that if two triangles have two congruent sides then the triangle with the larger angle between those sides will have longer third side

In ΔACD and ΔBCD

$AC = BC\\\angle ACD = 70 \angle BCD = 68$

So side opposite to greater angle is greater side

Therefore, length AD is greater than length BD.

On the function machine shown below, the function rule is given as a variable expression. When the output is 99, what is the inp

beks73 [17]

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2 - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1 =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.

646 is 85% of what number?

Lilit [14]

Let the number be y

The statement can be interpreted as

85% of y = 646

$\begin{gathered} \text{ }\frac{85}{100}\text{ x y = 646} \\ 85y\text{ = 64600} \\ y=\frac{64600}{85} \\ y=760 \\ \text{ The number is 760} \end{gathered}$
