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. 20.0 in. 23.1 in. 23.7 in. 27.4 in.

The perimeter of triangle is 23.7 in

Step-by-step explanation:

Please find the attachment for figure.

A right angle triangle measure 30°, 60° and 90°

whose hypotenuse is 10 inches

Let the side of triangles be a, b and c

where a and b are legs and c=10

Using trigonometry ratio:

The sides of right angle triangle are 10 in, 5 in, 8.66 in

Perimeter of triangle = a + b + c

                                    =  8.66 + 5 + 10

Perimeter of triangle = 23.66 ≈ 23.7 in

Hence, The perimeter of triangle is 23.7 in

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
