(6) QP = QR therefore, triangle QPR is an isosceles triangle.

Since QPR is an isosceles triangle, the base angles are equal.

angle P + angle R + 80 = 180

2x + 80 = 180

2x = 100

x = 50.

That is just the measure of the base angle.

Now take triangle TSR.

Since R = 50, due to angle sum property, we can come up with this equation:

50 + 85 + x = 180

x = 180 - 135

x = 45 <- That's the answer.

(8) Take triangle PSQ, you get angle P = 70 degrees using the angle sum property and algebra.

Now take triangle PSR and you get angle P in the triangle as (180 - 100) / 2 = 40.

Since P = 70, and P in the smaller triangle is 40, 70 - 40 would be the answer.

x = 30 degrees <- That's the answer :D

Answers

Answer: 75+50x= 105+35x , required equation.

Step-by-step explanation:

Let x = Number of days

Given:  Company "A" charges $75 plus a $50 a day.

Total charge = 75+50x

Company "B" charges $105 plus $35 a day.

Total charge = 105+35x

When both are same , equation becomes

75+50x= 105+35x

So, Required equation: 75+50x= 105+35x

You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?

Answers

Answer:

$19.79 cents (rounded to the nearest cent)

Step-by-step explanation:

first subtract the amount needed for materials from your total pay

(1000 - 525 = 475)

take 475 and divide that among the hours you work.

475 / 24 = 19.7916666

round that number to the closest money value
