Answer:

88.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation ...

Tan = Opposite/Adjacent

tan(10°) = x/500

x = 500·tan(10°)

x ≈ 88.2 . . . . units

_____

If you move the "500" dimension to the top of the figure, you see it is adjacent to the given angle, and the value x is opposite.

. FALSE

D) a unit rate always relates quantities with the same units. FALSE

Step-by-step explanation:

The ratio that which is used to compare quantities of different kinds is known as the rate of that quantity.

A unit rate is the ratio.

Number of units of the first type of quantity : Number of units of the second type of quantity.

I NEED HELPPP ON THIS PLZZZ

Anika [276]

Answer:

Perimeter of ABCD = 56 units

Perimeter of WXYZ = 140 units

Step-by-step explanation:

To find the perimeter of ABCD, find the sum of all sides

18 + 18 + 10 + 10 = 56

To find the side lengths of WXYZ, use the equation: $\frac{image}{pre-image}$

45/18 = 2.5

You can also cross multiply to find the missing side lengths, but I'll show you this other way...

Multiply the pre-image side lengths by 2.5

18 × 2.5 = 45

10 × 2.5 = 25

45 and 25 of the new side length of WXYZ

To find the perimeter of WXYZ, find the sum of all sides.

45 + 45 + 25 + 25 = 140

WX = 45, XY = 25, YZ = 45, ZW = 25
