Help, please, please!!

Step-by-step explanation:

The sum of the angles in a triangle is always 180 degrees.

40+3x+180-5x+10=180

-2x+50=0

-2x=-50

x=25

Again using the fact that the angles must have a sum of 180

40+3x+a=180

40+3(25)+a=180

40+75+a=180

a+115=180

a=65

So angle 1 is 65 degrees.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
