Answer:
40 feet
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
The area of triangle ABC is given as:
Area = (1/2) * AC * BC * sin(C)
But C = 50°, Area = 65.1 ft², BC = 10 ft, AC = b, AB = 13 feet.
Substituting gives:
65.1 = (1/2) * b * 10 * sin(50)
3.83b = 65.1
b = 17 ft
Perimeter of ΔABC = AB + AC + BC = 17 + 13 + 10
Perimeter of ΔABC = 40 feet
