PLEASE HELP, need RIGHT ANSWER also i will give brainliest ∠A and ∠B are supplementary angles. The measure of ∠A is three time the measure of ∠B.
Part A: Write an equation to represent the supplementary angle relationship between ∠A and ∠B.
Part B: Use the equation to find the measures of ∠A and ∠B.

a+b=c is your answer

yes

step-by-step explanation:

(2x+3)(x+5)(x-4)

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
