Each lapel on a suit jacket is in the shape of a triangle two of the three angles of each triangle measures 47 and 68 what is the measure of the third angle

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

because they could drop even lower..

it is 10.6 according to my calculations
