Answers

For question 1 the answer is b)

- Congruent angles have the same angle measure, and in a transversal, angles that are opposite around an intersection are congruent. For example ∠ 1 and ∠ 3 are congruent. Because the 2 lines are parallel (and intersected by the same line) the corresponding angles on the other intersection are also congruent. For example if ∠ 1 and ∠ 3 are congruent, then ∠ 5 and ∠ 7 are also congruent.

For question 2 the answer is b) 45°

- ∠ 3 and ∠ 4 are supplementary, meaning they equal 180° together. To solve you just need to subtract, 180° - 135° = 45°

For question 3 the answer is d) 145°

- This combines the previous 2 concepts. ∠ 1 and ∠ 5 are congruent (equal), ∠ 1 and ∠ 2 are supplementary. If ∠ 1 is 180° - 35° = 145°, and ∠ 1 and ∠ 5 are congruent, then ∠ 5 is also 145°.

For question 4 the answer is a) ∠ 1, ∠ 4, ∠ 5, and ∠ 8

- First,  ∠ 4 is supplementary because it falls along the same straight line (line m), similarly ∠ 1 is supplementary because it falls along a different straight line (the transversal). Because lines n and m are parallel and both intersected by the transversal, the corresponding angles, ∠ 5 and ∠ 8, are also supplementary.

For question 5, the answer is b) m∠ 3 = 70°

- ∠ 7 is supplementary to the 110°  angle, so m∠ 7 = 180°-110° = 70°,  ∠ 7 and  ∠ 3 are congruent, so m∠ 3 also equals 70°

Solve the equation for x. Check the solution.

2. -5(x + 3) = 20

Answers

Answer:

x = -7

Step-by-step explanation:

-5( x + 3 ) = 20

Distributive property ( multiply whatever is in the parenthesis by -5)

-5 * x + -5 * 3 = 20

-5x - 15 = 20

Add 15 on both sides

-5x - 15 + 15 = 20 + 15

-5x = 35

Divide by -5 on both sides to isolate the variable

-5x/-5 = 35/-5

x = -7

Check...

Substitute the "x" with -7 since we already got that as our solution

-5( x + 3 ) = 20

-5( -7 + 3 ) = 20

Distributive property

-5 * -7 + -5 * 3 = 20

35 - 15 = 20

20 = 20 CORRECT

Jim bought the game system on sale for $195. Kaylen bought the same system at full price for $250. How much was the sale for when Jim bought the game system?

Answers

Answer:

The game system that Jim bought had the sale of $55 off.

Step-by-step explanation:

Jim sale price = $195

Kaylen price = $250

[tex]250 -195 = 55[/tex]

since it’s $55 off, it was on sale for 22% off because 22% of $250 is 55 and 250-55= 195
