Which fraction is equivalent to 15 + 80?
15(1+4)
4(4 + 20)
3(5 + 20)
5(3+16

the fraction equivalent to 15+80 is 5(3+16)

Step-by-step explanation:

To check out work we can multiply the term outside the parenthesis with the term inside of it. So 5 times 3 is 15 and 5 times 16 is 80. Or also 15+80. That is the same as the expression above so that means 5(3+16) is equivalent to 15+80

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
