Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Sine = (opposite)/(hypotenuse)
5 is the opposite (opposite of the hypotenuse)
13 is the hypotenuse (longest side)
5/13, or <span>5 ÷ 13 is your answer

I think the answer is around 1.4 as you need to multiply the area by 1/9 after finding the real area.
Answer:
The answer should be B. 86.7
