Answer:
b. 24 yd
Explanation:
since we have a right triangle we have to apply the Pythagorean Theorem:, to find the missing side
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (10 yd) and a and b are the other sides.
Replacing with the values given:
10^2 = 6^2 + b^2
100 = 36+b^2
100-36 = b^2
64 = b^2
√64 = b
b= 8
Now, we can calculate the area:
A =1/2x base x height = 1/2 x 8 x 6 = 24 yd
