Remark

If the lines are parallel then triangle RQS will be similar to triangle RTP


From that, all three lines in one triangle will bear the same ratio to all three lines of the second triangle.


Givens

PQ = 8

QR = 5

RS = 15

ST = x + 3


Ratio

QR/RP = RS/RT


Sub and solve

RP = 5 + 8

RP = 13


RT = 15 + x + 3

RT = 18 + x


5/13 = 15 / (18 + x) Cross multiply

5(18 + x) = 195 Remove the brackets on the left.

90 + 5x = 195 Subtract 90 from both sides.

5x = 105 Divide by 5

x = 105/5

x = 21 Answer <<<<<<<

Can anyone me with this math question?
Anton [14]

This is geometry.. If lines l and M are parallel than we look at the line that goes from bottom left to the top right. this is called the transversal. When lines are parallel then alternate interior angles are congruent. That means opposite sides of the transversal and inside the parallel lines. That means 28 and  are congruent.

Your answer is 28..  I hope I helped you learn something..
