I need help on answering this question
liubo4ka [24]

Answer:

<h2>The answer is 72°</h2>

Step-by-step explanation:

Since < RQS = < QLK and < RQS = x

< QLK is also x

< QLK and < KLM lie on a straight line

Angles on a straight line add up to 180°

To find x add < QLK and < KLM and equate them to 180°

That's

< QLK + < KLM = 180°

x + x - 36 = 180

2x = 180 - 36

2x = 144

Divide both sides by 2

We have the final answer as

<h3>x = 72°</h3>

Hope this helps you

Zach is a shoe salesman, and he works on commission. This week, there is a special incentive to sell shoes and boots by a certai
Alexandra [31]

Answer:

Zach earns $10 and for the pair of boots Zach earns $15

Step-by-step explanation:

Let be x the number of pairs of shoes

Let be y the number of pairs of boots

Then we can establish the following system of equations with the data of the statement:

5x + 9y = 185 \\7x + 9y = 205

We subtract the second equation from the first equation to eliminate the variable y and solve for x, just like this:

7x+9y-5x-9y=205-185\\2x=20\\x=\frac{20}{2}\\x=10

For y replacing in the first equation the value of x and solving for y:

5.10 + 9y = 185\\9y=185-50\\y=\frac{135}{9}\\y=15

So for the pair of shoes Zach earns $10 and for the pair of boots Zach earns $15
