Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,

which is 40° and

which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,

:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Answer: 100°
No because the lines are not connecting. The definition of a function is a relationship involving one or more variables. This can't be a function because their is only one variable.
The answer is true the slope is the rate of change
5 1/3-1 1/3=4 u have the same denominators so u can subtract
