12. It takes James 20 minutes to ride his bike to the lake by one path, and 30 minutes to come back by a different path. If he goes to the lake and
back 4 times, how many minutes does he spend riding? Which gives the
answer? *
O (8+20) x (8+30) = 28 x 38 = 1,064 minutes
О
8 x 20 x 30 = 4,800 minutes
О
(8+8) X (20+30) = 16 x 50 = 800 minutes
O (8x20) + (8x30) = 160 + 240 = 400 minutes

step-by-step explanation:

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
