In the figure, TP and TS are opposite rays. TQ bisects ZRTP. S

If m2PTQ = 12x + 4 and mZRTQ = 15x – 5, find mZRTP.

∠ RTP = 80°

Step-by-step explanation:

Given that TQ bisects ∠ RTP , then

∠ RTQ = ∠ PTQ , substitute values

15x - 5 = 12x + 4 ( subtract 12x from both sides )

3x - 5 = 4 ( add 5 to both sides )

3x = 9 ( divide both sides by 3 )

x = 3

Thus

∠ RTP = ∠ PTQ + ∠ RTQ = 12x + 4 + 15x - 5 = 27x - 1 = 27(3) - 1 = 81 - 1 = 80°

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

other answer is correct. i had used the radius of the radius somehow. a website:
