Answer:
105
Step-by-step explanation:
The interior angle for R is supplementary to the 155 degree angle
(they add to 180)
180-155=25
The sum of the interior angles of a triangle is always 180
180-50-25= 105
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.

Ittttts obviously be greater than 3/5
5 * 3/5 to get 3!!
