Answer:
41
Step-by-step explanation:
6^2 + 5^2 = 61
61 - (5 x 4) = 61 - 20 = 41
3K= I-14j which then equals K=(I-14J)/3
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.
