If &A and B are a linear pair and m&A = 2x + 8 and m&B = 3x + 2, what is the value of x? *
Your answer
If 4A and B are vertical angles and m&A = 7x - 5 and m&B = 4x + 10, what is the
value of x? *
Your answer

34;

5

Step-by-step explanation:

1. m<A = 2x + 8 (given)

m<B = 3x + 2 (given)

Since <A and <B are a linear pair, therefore:

m<A + m<B = 180° (angles in a linear pair add up to 180°)

(2x + 8) + (3x + 2) = 180 (substitution)

Solve for x

2x + 8 + 3x + 2 = 180

Collect like terms

5x + 10 = 180

Subtract 10 from each side of the equation

5x = 180 - 10

5x = 170

Divide both sides by 5

x = 34

2. m<A = 7x - 5 (given)

m<B = 4x + 10 (given),

Since m<A and m<B are vertical angles, therefore:

m<A = m<B (vertical angles are congruent)

7x - 5 = 4x + 10 (substitution)

Subtract 4x from both sides

7x - 5 - 4x = 4x + 10 - 4x

3x - 5 = 10

Add 5 to both sides

3x - 5 + 5 = 10 + 5

3x = 15

Divide both sides by 3

3x/3 = 15/3

x = 5
