Answer:
4x -51
Step-by-step explanation:
m(n(x)) = m(x - 10) = 4(x-10) - 11 = 4x -40 -11 = 4x -51
I prefer decimals with common denominators so I'm going to go ahead and convert them.
-1.25+.50 = -.75
-.75 is -3/4 aka "c" or the third option.
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°
