I don’t know if 8/20 is greater than 15/20. And I don’t know 2/5 is greater than 3/4

15/20 is greater than 8/20 and 3/4 is greater than 2/5.

Step-by-step explanation:

15/20 is greater than 8/20 because 15 is a bigger number than 8 (over the name denominator of course.

However, the second one requires more work.

Basically you want to make their denominators the same.

I will mulitply 3/4 by 5.

that equals 15/20.

I will mulitply 2/5 by 4.

That equals 8/20.

Thus, 3/4 is greater than 2/5.

And 3/4 is equal to 15/20.

And 2/5 is equal to 8/20.

Hope this helped! :)

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
