The value of -18/15 · 20/24 is .

I think that the value is -1/2

Because firstly you have to make it easier to read like that : (-1x3x2x3)x(2x5x2) / ( 3x5)x(3x4x2)

Then you can just cross out the one you see in the numerator and denominator . Then you have something like -1/2 with what you didn’t cross out.

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
