yulyashka [42]

Answer:

m<S = 45°

Step-by-step explanation:

The sum of the measures of the angles of a triangle equals 180 deg.

m<R + m<S + m<T = 180

3x + 2x + 3x = 180

8x = 180

x = 22.5

m<S = 2x = 2(22.5) = 45

Use the law of sines to find what Angle R is:
stich3 [128]

Answer:

Step-by-step explanation:

So, according to the law of Sines, we have

\frac{Sin(A)}{a} = \frac{Sin(b)}{b}

In our case, we have S and R, so...

\frac{Sin(S)}{s} = \frac{Sin(R)}{r}

And we want to isolate R...

r = sin^{-1} (\frac{Sin(S) * r}{s} ) = sin^{-1} (\frac{Sin(52) * 32}{26} ) = 75.90

the angle of R is then 75.90 degrees.
