Answer:
116°
Step-by-step explanation:
The angles of any triangle will add up to 180°. Since we know the measures of ∠SPR and ∠PRS, we can find the measure of ∠PSR by adding the two measures and subtracting from 180°.
Now we know the measure of ∠PSR. Note that ∠PSR is supplementary to ∠PST, meaning that both values add up to 180. Let's do the math then.
This means that the measure of ∠PST is 116°.
Hope this helped!

Step-by-step explanation:
sin(α + β) = sin α cos β + sin β cos α
sin(α - β) = sin α cos β - sin β cos α
[ sin(α + β) + sin(α - β)] =
[sin α cos β + sin β cos α + sin α cos β - sin β cos α]
= [2 sinα cos β]
= sin α cos β = [ sin(α + β) + sin(α - β)]
