Algebra 1a connections academy 10th grade unit 6: lesson 9: portfolio how do i write an equation if i don't have a constant of proportionality?me asap! 10 points and brainliest if answered correctly! you! : )

Well the constant of variation is vital yet if there is a graph, table, or two points provided then you can find the slope. You will have to use different equations and steps of course.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
