Step-by-step explanation:
The area of a triangle is given by
where
is the base of the triangle and
is the height of the triangle. In a right triangle, the two legs will represent the base and height, both interchangeable.
In a 30-60-90 triangle, the sides are in the proportion
, where
is the hypotenuse of the triangle and
is the side opposite to the 30 degree angle. Since the hypotenuse of this triangle is given as 10, the leg opposite to the 30 degree angle is equal to
and the leg adjacent to the 30 degree angle is equal to
.
Thus, the area of this triangle is equal to:

Answer:
Youngest: 13 years old
Middle: 18 years old
Oldest: 26 years old
Step-by-step explanation:
2c + c+5 + c = 57
4c = 52
c = 13 years (youngest)
a = 2c = 26 years (oldest
b = c+5 = 18 years (middle)
