What is the measure of < 1? what is the measure of < 2? what is the measure of < 3?

Angle 1: 37º

Angle 2: 127º

Angle 3: 23º

Step-by-step explanation:

angle 1:

the square angle is 90 so add 53 + 90 = 143

every triangle has a total angle sum of 180 so subtract 143 from 180 to get 37

angle 2:

is supplementary to the angle of 53º so subtract 180 - 53 = 127

angle 3:

add 127 + 30 = 157 and subract it from 180

180 - 157 = 23

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
