Answer:

see explanation

Step-by-step explanation:

x and x - 20 are adjacent angles and are supplementary , thus

x + x - 20 = 180

2x - 20 = 180 ( add 20 to both sides )

2x = 200 ( divide both sides by 2 )

x = 100

x - 20 = 100 - 20 = 80

------------------------------------------------------------

11x - 2 and 75 are corresponding angles and are congruent, thus

11x - 2 = 75 ( add 2 to both sides )

11x = 77 ( divide both sides by 11 )

x = 7

11x - 2 = 11(7) - 2 = 77 - 2 = 75

HELPPPP !! Find the measure of angle LMN if the measure of angle LMP is 107 !!

Answers

Answer:

m∠LMN = 29°

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Set up equation

m∠LMN and m∠NMP must add up to m∠LMP

(2x - 1)° + (5x + 3)° = 107°

Step 2: Solve for x

Combine like terms:                    7x + 2 = 107Isolate x term:                              7x = 105Isolate x:                                       x = 15

Step 3: Find m∠LMN

Define:                    m∠LMN = (2x - 1)°Substitute in x:       m∠LMN = (2(15) - 1)°Multiply:                  m∠LMN = (30 - 1)°Subtract:                 m∠LMN = 29°

help me please, what are the like terms?

Answers

Step-by-step explanation:

Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.
