No because 4 square equals 2 square and since 3 isn't a perfect number, it would be 2 square times 3 square, which equals 6 square.

3^2 • 4^2 = 12
9 • 16 = 12
144 = 12

144 is not equal to 12, so this equation is false.

Which proportion could be used to find the length of side b?

Goshia [24]

Answer:

Step-by-step explanation:

Using the Sine Rule in ΔABC

$\frac{a}{sinA}$ = $\frac{b}{sinB}$ = $\frac{c}{sinC}$

∠C = 180° - (82 + 58)° = 180° - 140° = 40°

Completing values in the above formula gives

$\frac{a}{sin58}$ = $\frac{b}{sin82}$ = $\frac{8.4}{sin40}$

We require a pair of ratios which contain b and 3 known quantities, that is

$\frac{b}{sin82}$ = $\frac{8.4}{sin40}$

$\frac{sin40}{8.4}$ = $\frac{sin82}{b}$ → B

Hey there! :)

Answer:

x = 242 mm.

Step-by-step explanation:

Begin by setting up a proportion between the actual college building and the drawing.

$\frac{22mm}{9m} = \frac{x}{99m}$

Cross multiply:

99 × 22 = 9 × x

2178 = 9x

Divide both sides by 9:

2178/9 = 9x/9

x = 242 mm.
