Answer :

The change of occurring an event is known as Probability.

You can solve probability questions by following some formulas

Conditional probability- P ( A l B ) = P ( A ^ B ) / P (B)

Bayes - P (A l B) = P (B l A)

P (A) / P (B)

Complementary- P(A^c) + P (A) = 1

A Ladder that is 32 ft long leans against a building. The angle of elevation of the ladder is 70 degrees. To the nearest tenth o

kolezko [41]

See the picture attached to better understand the problem

we know that
in the right triangle ABC
sin 70°=opposite side angle 70°/hypotenuse

in this problem
opposite side angle 70°=AB
hypotenuse=AC----> 32 ft
sin 70°=AB/32------> AB=32*sin 70°-----> AB=30.07 ----> AB=30.1 ft
