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:~

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

136ﾟ is the same as ___ radians<br> Round to the nearest hundredth of a radian

Crazy boy [7]

to change from degrees to radians

multiply by pi/180

136 * pi/180 = 136/180 * pi

now simplify

34/45 * pi

.755556 * pi pi=3.14159

2.373648

to the nearest hundredth

2.37 radians

Amelia wants to paint three walls in her family room two walls are 26 feet long by 9 feet wide the other wall is 18 feet long by

Svetllana [295]

26 by 9
Area = L*W
Area = 26 * 9
Area = 234 square feet but there are 2 such walls
Area = 234 * 2
Area = 468 square feet total for these walls.

18 by 9
Area = L*W
Area = 18 * 9
Area = 162 square feet

Total area = 468 + 162 = 630 square feet.

1 gallon covers 250 square feet
x gallon covers 630 square feet

1/x = 250/630
250 x = 1 * 630
x = 630 / 250
x = 2.52 gallons. It is best that she buy 3 gallons of paint.

A property of rectangles is that opposite sides are congruent. In this case, since QT and RS are opposite sides, they are equal to each other. With this knowledge, you can form the equation $50=4x+8$ to solve for x.
