b. 4
c. 8

The answer is A. (42)

WORKINGS

Since Q is equidistant from the sides of ∠TSR,

∠TSQ = ∠QSR

m∠TSQ = 4x + 5

m∠QSR = 8x – 11

Therefore, 4x + 5 = 8x – 11

Solving for x

4x + 5 = 8x – 11

Add 11 to both sides of the equation

 4x + 5 + 11 = 8x – 11 + 11

4x + 16 = 8x

Subtract 4x from both sides of the equation

4x + 16 – 4x = 8x – 4x

16 = 4x

4x = 16

x = 16/4

x = 4

∠RST is the same as ∠TSR

m∠RST = ∠TSQ + ∠QSR

m∠RST = 4x + 5 + 8x – 11

m∠RST = 12x – 6

m∠RST = (12 x 4) – 6

m∠RST = 48 – 6

m∠RST = 42 degrees

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
