(4x + 23)
(2x + 37)
Q=

R is 51 degrees

P is 51 degrees

Q is 78 degrees

Step-by-step explanation:

This is an isosceles triangle so R and P are the same angle degree.

First set them equal to each other to be (4x+23)=(2x+37) to get x=7.

Substitute X with 7: 4(7)+23=2(7)+37. It will be 51=51.

A triangle is equal to 180 degrees so 51+51 is 102 and 180-102 is 78.

Hope this helped :)

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
