Answer:

∠ XZY ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle, that is

sinXZY = $\frac{opposite}{hypotenuse}$ = $\frac{XY}{YZ}$ = $\frac{6}{15}$ , then

∠ XZY = $sin^{-1}$ ( $\frac{6}{15}$ ) ≈ 23.6° ( to 1 dec. place )

If on a scale drawing 24 inches equals 10 ft. what does 1/8 inches equal

OLga [1]

Answer:

$\large\boxed{\large\boxed{(5/96)ft\approx 0.052ft}}$

Explanation:

1. Use the scale ratio to set a proportion with the unknown lenght.

$24inches/10ft=(1/8)inches/x$

2. To solve for x, use cross multiplication:

$24inches\times x=10ft\times(1/8)inches$

3. Divide both sides by 24inches:

$x=10ft\times(1/8)inches\times (1/24inches)$

4. Simplify:

$x=10ft/192=(5/96)ft\approx 0.052ft$
