Answer:
Measure of <QTS = 20°
Measure or minor arc QS = 40°
Step-by-step explanation:
From the figure we can see a circle with center U.
<u>To find the measure of <QTS</u>
m<QTS = m<QPS [Angles subtended by same arc are equal]
Therefore m<QTS = 20°
<u>To find the measure of minor arc QS</u>
Measure or minor arc QS = 2 * m<QPS
= 2 * 20 = 40°
Measure or minor arc QS = 40°

Answer:
A 1,3,10.
Step-by-step explanation
3, 4, 10. This means that 3 and 4 are the lengths of the legs and 5 is the hypotenuse.
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Mrs Kennedy is buying pencils for 315 students.
The pencils are sold in boxes of 10.
Therefore the number of pencils she needs to buy should be a multiple of 10, so that she can buy boxes of 10 pencils each.
number of students are 315 but 315 is not a multiple of 10
so we have to round off 315 to the nearest ten, that's 320.
so then she has to buy 320 pencils
number of boxes she needs - 320 / 10 = 32 boxes of pencils
she only needs pencils for 315 students so she will have 5 extra pencils
she will have to buy 32 boxes
