Atriangle has angles that measure 30o, 60o, and 90o. the hypotenuse of the triangle measures 10 inches. which is the best estimate for the perimeter of the triangle? round to the nearest tenth.

Given: In Δ ABC, ∠B =90° , ∠C = 30° , ∠A = 60° and Hypotenuse AC = 10 inches

It has been described in the attachment.

Now, we shall calculate side AB and BC by using Trigonometric Ratios.

Sin 30° = AB / AC

or,     AB = 10 × Sin 30° = 10 × 0.5 = 5 inches

And,  Cos 30° = CB / AC

or,               CB =  10 × Cos 30° = 10 × 0.866 = 8.66 inches

Now, we shall calculate the perimeter of the given triangle

Perimeter of the triangle = AB + BC + CA

or,                                      = (5.0 + 8.66 + 10.0 ) inches

or,                                      = 23.66 inches ≈ 23.7 inches

Hence, the best estimate for the perimeter of the triangle ( round to the nearest tenth will be 23.7 inches.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

the answer to question 1 is -8, 28.
