(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

ron wants to buy a video game with a selling price of $60, on sale for 50% off. The sales tax in 4.5% state is . How much will he have to pay in all? If has $34, can he afford to purchase the game?
Answer:
Yes, he can.
Step-by-step explanation:
To find the sale, you need to times the sale percentage by the original price so
60 x 0.50 = 30
Then you subtract the original price by the sale price so
60 - 30 = 30
So the with the sale, the price is $30.
Now the tax
Do the same
30 x 0.045 = 1.35
Now instead of subtracting you add so
30 + 1.35 = $31.35
Yes, he can afford it.
At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student
Answer: 3.75
Step-by-step explanation:
The following can be gotten from the question:
Time taken for each session = 4/5 hours
Total time set aside by principal = 3 hours
The number of sessions that can be sheduled for each student will be:
= Total time set aside by principal / time taken for each session
= 3 hours / 4/5 hours
= 3 × 5/4
= 3.75

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 18 fl oz per . How fast was the pipe leaking in gallons per ?
Answer:
0.140625 gallons per
Step-by-step explanation:
By doing a quick search we discover that there are 1 fl oz is equal to 0.0078125 gallons. Therefore, in order to find out how fast the pipe was leaking in gallons, we simply multiply the rate of fl oz by the number of gallons for every fl oz like so...
18 fl oz * 0.0078125 gallons = 0.140625 gallons
