PLS WILL GIVE 100 POINTS AND MARK BRAINLEST

angle 2 = 128 because of a rule that I unfortunately cannot remember the name of

angle 6 = 180 - 47 = 133

because a straight line = 180 degrees

angle 3 = 180 - 128 = 52

Same reason as angle 6

angle 1 = 52 + 47 = 99

180 - 99 = 81

Sum of the angles in a triangle = 180

All of the underlined numbers are the answers

Step-by-step explanation:

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
