Answer: Option C. (ST, TR, SR)
WORKINGS
Given,
m∠R = 37
m∠S = 50
m∠T = ?
m∠R + m∠S + m∠T = 180 (Sum
of angles in a triangle)
37 + 50 + m∠T = 180
87 + m∠T = 180
Subtract 87 from both sides of the equation
87 – 87 + m∠T = 180 – 87
m∠T = 93
Therefore the angles of the triangle, in order from smallest
to largest: ∠R, ∠S, ∠T
∠R is opposite ST
∠S is opposite TR
∠T is opposite SR
Therefore, the side lengths of the triangle in order from
shortest to longest: ST, TR, SR (Option C)

Thanks.
Step-by-step explanation:
By inscribed angle theorem:
Answer:
x > -9
See the second scenario if incorrect.
Step-by-step explanation:
1...x^(2) + 9x < 0
first factor
2...x * ( x + 9 ) < 0
now divide by x
note: 0 divided by any number is 0
2... x * ( x + 9 ) < 0
/x /x
3... x + 9 < 0
now subtract 9
3... x + 9 < 0
-9 -9
4... x< -9
Second scenario
In the event that x is a negative number
2... x * ( x + 9 ) < 0
dividing by x will flip the inequality sign
(3)... x + 9 > 0
subtract 9
(3)... x + 9 > 0
-9 -9
(4)... x> -9
