<u>Lower half of the data: </u>

  • 15, 19, 20

<u>Lower quartile:</u>

  • mid term of 15, 19, 20 = 19

Angle T has a measure between 0° and 360° and is coterminal with a –710° angle. What is the measure of angle T?
disa [49]

To find the coterminal angle to the given angle , we need to add or subtract the multiples of 360 degree . Since here we have to find the coterminal of -710 in 0 to 360, it means we have to find a positive coterminal angle . And to find the positive coterminal angle, if we add just 360 degree, we will get -710+360 = -350, but we need a positive coterminal angle, so we add again 360 , that is -350+360 =10.

So the coterminal of -710 in 0 to 360 is 10 degree .

Korvikt [17]
Since the pool is square, the four sides are equal.
Therefore the length of one side = sqrt(292) = 17.1 to the nearest tenth.
