Why is ac smaller than ad if they both look very close

kakasveta [241]

Let's begin by listing out the information given to us:

We start out by observing that Triangles MKR & ACD are similar or proportional

$\begin{gathered} MK=21;AC=\text{?} \\ MR=24;AD=28\frac{4}{5} \\ KR=CD=\text{?} \end{gathered}$

We will solve for the missing side by using the similar triangle theorem. This is shown below:~

$\begin{gathered} \Delta MKR\approx\Delta ACD \\ \frac{MK}{AC}=\frac{MR}{AD} \\ \frac{21}{AC}=\frac{24}{28\frac{4}{5}} \\ \text{Cross multiply, we have:} \\ 24\cdot AC=28\frac{4}{5}\cdot21 \\ AC=\frac{28\frac{4}{5}\cdot21}{24}=25\frac{1}{5} \\ AC=25\frac{1}{5} \end{gathered}$

Solve the equation<br> 5.4/12 = z/8

saul85 [17]

Answer:

18/5

Step-by-step explanation:

5.4/12 = 1/8 is equivalent to (5.4)(1/12) = (z/8), or

(54/10)(1/12) = z/8.

The LCD is (10)(8)(12), or 120.

Mult. both sides by 120 yields 54 = 15z.

Dividing both sides by 15, we get z = 54/15 = 18/5 = z
