Theres a triangle with the angles, 9in 7in 13in 18in, what is the answer? 40 inches squared 40 inches squared 63 inches squared 63 inches squared 126 inches squared 126 inches squared 47 inches squared 47 inches squared
To find the area of a triangle, you can use the formula:
Area = 1/2 * base * height
To find the height of the triangle, you can use the formula:
height = sqrt(legs^2 - (base/2)^2)
In this case, the base is 13 inches and the legs are 9 inches and 7 inches.
Substitute the values into the formula to find the height:
height = sqrt(9^2 - (13/2)^2) = sqrt(81 - 42.25) = sqrt(38.75) ≈ 6.22 inches
Now, calculate the area of the triangle:
Area = 1/2 * base * height = 1/2 * 13 * 6.22 = 40.63 inches squared
Therefore, the answer is approximately 40.63 inches squared.
