What is the measure of angle w? Type the number only. Do not type the word degrees.
Margaret [11]

Answer:

w = 34°

Step-by-step explanation:

Every quadrilateral is equal to 360 degrees. If you know 3 out of the 4 angles, then what you need to do is add up each angle and subtract the sum from 360 to find the remaining angle.

90 + 90 + 146 = 326

360 - 326 = 34

w = 34

Find the average rate of change of f(x)= x^2-5x+2 from x=3 to x=8.
kolezko [41]
Rate of change will be the difference in f(3) and f(8). solve for the 2 first:
f(3)=3²-5(3)+2 = -4
f(8)=8²-5(8)+2 = 26

than find the difference in f(3)-f(8)= -4-26  = -30
