Greatest whole number lying between -16 and 2​
Lostsunrise [7]

Answer:

<em>The threatest whole number in the interval is 2</em>

Step-by-step explanation:

<u>Numbers and intervals</u>

We are given the interval of numbers between -16 and 2. Since it's not specified, both endpoints of the interval are not included.

If we consider the interval as real numbers, then there are infinitely many numbers there, like -15, -12.56, -8, -2pi, 0.02, 1.99.

If we are restricted to only whole numbers, then we get a limited set of the numbers: {-15, -14, -13, -12,....,1}

Note the greatest number at the right endpoint of the interval is 1, since we are not including 2.

The threatest whole number in the interval is 2

Find the measure of y.<br><br> picture included <br><br> PLEASE HELP
pochemuha

Answer:

90 degrees

Step-by-step explanation:

Hello there!

The triangle shown inside of the circle is formed with the diameter.

The diameter stops at a tangent line forming three angles

y, the one inside of the triangle and the other interior angle

Remember the diameter splits the circle in half and if the diameter intersects with a tangent line then its going to form 2 right angles

so we can conclude that the measure of y is 90 degrees
