Question

In ΔRST, r = 5 cm, t = 6.8 cm and ∠T=23°. Find all possible values of ∠R, to the nearest 10th of a degree.

Answer 1

`\angle r=16.696`

Explanation:

From the question we are told that:

Dimension

r = 5 cm

t = 6.8 cm

∠T=23°

Generally the equation of sine rule i is mathematically given by

`(sin \angle r)/(R) =(sin \angle t)/(T)`

`( \angle r)/(1) =sin^-^1((sin \angle t*R)/(T))`

`( \angle r)/(1) =sin^-^1((sin23*5)/(6.8))`

`\angle r=16.696`
