In a 30-60-90 triangle, the length of the side opposite the 30 degree angle is 8. Find the length of the side opposite the 60 de

nalin [4]

Answer:

The length of the side opposite the 60 degree angle 'c' = 4

Step-by-step explanation:

Step(i):-

Given data ∠A = 90° , ∠B = 60° and ∠C = 30°

Given data the length of the side opposite the 30 degree angle is 8

let 'a' = 8

step(ii):-

By using sine rule formula in properties of triangle

$\frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C} = 2 R$

$\frac{a}{Sin A} = \frac{c}{Sin C}$

$\frac{8}{Sin 90} = \frac{c}{Sin 30}$

cross multiplication , we get

$\frac{8 X sin 30}{Sin 90} = c$

we know that trigonometry formulas

sin 30° = $\frac{1}{2}$ and sin 90°= 1

C = 8 X 1/2 = 4

conclusion:-

The length of the side opposite the 60 degree angle 'c' = 4

Your utility expense grew from $233 to $267. In the same period, your staffing expense grew from $1,266 to $1,411. Which expense

jeyben [28]

Increase in utilities = 267 - 233 = 34

For $233, increase = $34

For $100, increase = $\frac{34}{233} (100)$

= 14.59%

Increase in staffing expense = 1411 - 1266 = 145

For $1266, increase = $145

For $100, increase = $\frac{145}{1266} (100)$

=11.45%

Hence, utilities had the higher percentage growth rate.
