Find the value of x.

x=75

Step-by-step explanation:

you have to 140 and the other side doesn't have anything so you take 180 and subtract it by 140 180-140=40 so the inside angle is 40 and since you have two angles in the triangle you add them then subtract it by 180 180-(40+35)=105 so now you have the last angle for the inside so then you subtract that angle to get x 180-105=75 so 75=x

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
