Answer:

∠B = 60°

a = 4.0 units

b = 6.9 units

Step-by-step explanation:

The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.

The 3 angles are 90, 30 , ∠B .

<em>90+30+B = 180</em>

Thus, B = 180 - 120 = 60 degrees

by trigonometry,

sin(30) = \frac{a}{8} = 0.5

a = (8)(0.5) = 4 units

Also,

cos(30) = \frac{b}{8} = 0.866

b = (8)(0.866)= 6.928

Black_prince [1.1K]
\bf \cfrac{\quad \frac{3}{4}\quad }{\stackrel{\textit{two dozen}}{24}}\implies \cfrac{\quad \frac{3}{4}\quad }{\frac{24}{1}}\implies \cfrac{3}{4}\cdot \cfrac{1}{24}\implies \cfrac{3}{96}
