BC is 21 meters.
2x + 5 + 3x = 45
5x + 5 = 45
5x = 40
X = 8
2(8) + 5 = BC
21 = BC
The answer to the question is 21.333 yards
Answer:
24
Step-by-step explanation:
I will assume this is a right triangle with the information given
a^2+b^2 = c^2 is the Pythagorean theorem
18^2 + b^2 = 30^2
Subtract 18^2 from each side
18^2 - 18^2+ b^2 = 30^2 -18^2
b^2 =900 -324
b^2 =576
Take the square root of each side
sqrt(b^2) = sqrt(576)
b =24
Area = π x r^2
Area = π x 12^2
Area = 144π or 452.16 square units. ( using 3.14 for PI)
Circumference = 2*PI *radius
Circumference = 12π or 37.68 units ( using 3.14 for PI)
