The map of a biking trail is drawn on a coordinate grid. the trail starts at p(−3, 2) and goes to q(1, 2). it continues from q to r(1, −1) and then to s(8, −1). what is the total length (in units) of the biking trail? 11 13 14 16

Third option is correct. The total length of biking trial is 14 units.

Step-by-step explanation:

It is given that the trail starts at P(−3, 2) and goes to Q(1, 2).  It continues from Q to R(1, −1) and then to S(8, −1).

The distance formula is

We have to find PQ, QR and RS.

The total length of h trail is

Therefore total length of biking trial is 14 units.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

y=1/4x-4
