A = {multiples of 2}, B = {multiples of 3), C = {multiples of 7}. If n(A n B n C} = 1 what can you say about $(the universal set).

Let's check the sets

Find LCM

Recreate the sets

Now

Hence

Universal Set =U

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

i cant answer this, theres no table. sorry man
