Sin 23° = Opposite/Hypotenuse = b / c
0.39 = b / 30
b = 0.39 · 30
b = 11.722 cm
Area of a triangle:
A = 1/2 b h
A = 1/2 · 11.722 · 27.6
A ≈ 161.7 cm²

Solve the equation<br> 3x/ 8 - 4x/3 =4

Virty [35]

Answer:

x = -96/23

Step-by-step explanation

$\frac{3x}{8}$ - $\frac{4x}{3}$ = 4

multiply each side of equation by 24 to eliminate denominators

(24) $\frac{3x}{8}$ - $\frac{4x}{3}$ = 4 (24)

3(3x) - 8(4x) = 96

9x - 32x = 96

-23x = 96

x = -96/23
