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.
Answer:

Step-by-step explanation:
parabola equation with vertex (0 , 0) and focus length |f| = 7
4*f*(x - h) = (y - k)²
4*7*(x-0)=(y-0)²
28x = y²

Answer:
The
have the wrong values.
Step-by-step explanation:
The point (-7,-24) lies in the third quadrant, where the only tangent function will have a positive value and all the other trigonometric functions are negative.
The origin has a distance from the point is
.
If the point makes an angle
with the negative x-axis, then






Therefore, the
have the wrong values. (Answer)
