A blindfolded marksman finds that on an average, he hits the target 7 times out of 10. If he fires 9 shots, what is the probability of

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

you need to give us more information since we can't answer

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392
