The tropics account for about 36 percent of Earth, and about a third of the world's population lives in this area... In this sentence

1) What does the phrase mean ' a third of the world's population lives in this area '?

2) How much is 'a third' ?

​

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

86

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2

answer: (x+2) (x+3) are the binomials for your question : )
