Answer:

b. 3

Step-by-step explanation:

In a 30°-60°-90° triangle, the short side is ½ the hypotenuse [the long side is double the short side].

30°-60°-90° Triangles

x√3 → long side

x → short side

2x → hypotenuse

45°-45°-90° Triangles

x → two legs

x√2 → hypotenuse

frozen [14]

Area, A = Width, W* Height, H

Therefore,
W = A/H

Options:
At H = 4 ft, W = 60/4 = 15 ft
At H = 5 ft, W = 60/5 = 12 ft
At H = 6 ft, W = 60/6 = 10 ft

Answer:

$9x- 60=10$

Step-by-step explanation:

Given

$\frac{3}{4}x - 5 = \frac{5}{6}$

Required

Rewrite to remove fractions

The denominators in the above expression are 4 and 6.

So, first we take the LCM of 4 and 6

$LCM = 12$

Next, multiply both sides of the equation by this LCM (12)

$12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12$

$12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12$

$3 * 3x- 60=5 * 2$

$9x- 60=10$

$\bf \stackrel{\textit{she subtracted }\frac{2}{3}\textit{ instead of adding it}}{-\cfrac{11}{6}-\left(\cfrac{2}{3} \right)\impliedby \stackrel{LCD}{6}\implies \cfrac{-(1)11~~-~~(2)2}{6}}\implies \cfrac{-11~~-~~4}{6}
\\\\\\
\cfrac{-15}{6}\implies \stackrel{simplified}{-\cfrac{5}{2}}\impliedby \textit{that's correct, assuming is }\frac{2}{3}~~but~is~~-\frac{2}{3}\\\\
-------------------------------$

$\bf \stackrel{\textit{recall that minus times minus is plus}}{-\cfrac{11}{6}-\left(-\cfrac{2}{3} \right)\implies -\cfrac{11}{6}+\cfrac{2}{3}}\implies \cfrac{-(1)11+(2)2}{6}
\\\\\\
\cfrac{-11+4}{6}\implies -\cfrac{7}{6}\quad \checkmark$
