Answer:
5/4
Step-by-step explanation:
The relationship between the sec and csc functions is ...
csc(A) = sec(A)/√(sec²(A) -1)
For the given value of sec(A), this is ...
csc(A) = (5/3)/√((5/3)² -1) = (5/3)/√(16/9) = (5/3)/(4/3)
csc(A) = 5/4

Answer:
116°
Step-by-step explanation:
In a triangle, the sum of all interior angles is 180°
<PRS + <RSP + <SPR = 180°
51° + <RSP + 65° = 180°
<RSP = 180° - 65° - 51° = 180° - 116° = 64°
Since, <PST and <RSP are supplementary angles,
<PST + <RSP = 180°
<PST = 180° - 64° = 116°
