In ΔRST, r = 210 inches, t = 550 inches and ∠T=166°. Find all possible values of ∠R, to the nearest degree.
valkas [14]

Answer:

m(∠R) = 5°

Step-by-step explanation:

By applying sine rule in the given triangle RST.

\frac{\text{sin}(\angle R)}{ST}= \frac{\text{sin}(\angle T)}{SR}

\frac{\text{sin}(\angle R)}{r}= \frac{\text{sin}(\angle T)}{t}

\frac{\text{sin}(\angle R)}{210}= \frac{\text{sin}(166)}{550}

sin(∠R) = \frac{210\times \text{sin}(166)}{550}

           = 0.09237

m(∠R) = \text{sin}^{-1}(0.09237)

           = 5.3°

           ≈ 5°

Carla is going to arrange her 4 books on a shelf: Algebra, Trigonometry, Geometry and Calculus. How many different possible arra
PilotLPTM [1.2K]

Arranging of books is an illustration of permutation and combination

There are 24 different possible arrangements she can make

<h3>How to calculate the number of arrangement</h3>

The number of books is given as:

n = 4

Take the factorial of both sides

n! = 4!

Evaluate

n! = 4 * 3 * 2 * 1

n! = 24

Hence, there are 24 different possible arrangements she can make
