Angles ptq and str are vertical angles and congruent. circle t is shown. line segments t p, t q, t r, and t s are radii. lines are drawn to connect the points on the circle and form secants p q, q r, r s, and s p. angles p t q and s t r are congruent. which chords are congruent?

30,40,50 is correct answer

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
