Answer:

The answer is option A.

Step-by-step explanation:

Angles in a triangle add up to 180°

To find y add up all the angles and equate them to 180°

That's

y + 40 + y + 30 = 180

2y = 180 - 70

2y = 110

Divide both sides by 2

Hope this helps you

I don't understand proportional relationship can u help?

Reptile [31]

Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D
