What is the measure of ZB of the pentagon?

111°

Step-by-step explanation:

The sun of interior angles in a pentagon is 540° so to find the measure of B we gotta add all given measure up then subtract it from 540

150° + 98° + 89° + 92° + B = 540° ➡ B = 111°

answer: the first graph

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
