Help ! need an explanation and answer!

as below

Step-by-step explanation:

because the interior angles add up to 180 degrees.. you can solve this

180= 32 + 64 + x    hmm

84 = x

so the last angle is 84°    :)

as we know that the sum of three interiors angle = 180

Two angles are given 32 and 64

let the angles be a , b and c

A + B + C = 180

32 + 64 + C = 180

C = 180-96

C = 84

Hence the 3rd angle is 84

hope it helps u

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

the correct answers i think are b. and d.

give me brainliest if it is correct!
