Answer:
17
Step-by-step explanation:
because 19 students for the other in total (you add the ones who study biology and the ones who study both, then you minus the group of students by 19)
I think it would be 1462 yards
It is seen in the figure given that there are three triangles with sides equal to a = 17 inches, b = 17 inches, and c = 20.5. Our angle c is the angle opposite side c and that is 74°. Using the equation given in the question,
A of triangle = ((17 in)(17 in)(sin 74°))(1/2)
= 138.9 in²
Then, we multiply this area by 3 since there are 3 triangles.
total area = (138.9 in²)(3) = 416.7 in²
The area of the figure is most approximately equal to 417 in².
100% = 25 so 25 + 15%
15% = .25 (25 divided by 100= .25) x 15 = 3.75
25 + 3.75 = 28.75 so C
