3. A box contains 8 red shirts, 7 blue shirts, 10 red pants, and 15 blue pants. Determine the probability of randomly selecting a blue piece of clothing or a pair of pants. Use PA a B) = P(A) + P(B) - PA and B) to
explain your answer. PLEASE WRITE YOUR FINAL ANSWER AS A SIMPLIFIED FRACTION.

after simplifying it i got: -36.25 as my answer. hope that !

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
