(GEOMETRY)Lian is making a banner for the school gym. She cut three pieces of fabric into congruent isosceles triangles, as show
oksano4ka [1.4K]
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.

9. Write an equation of a parabola that opens to the right, has a vertex at the origin, and a focus at (7,0).
Nookie1986 [14]

Answer:

x = \frac{1}{28} y^{2}

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

x = \frac{1}{28} y^{2}

The point (-7, -24) is on the terminal ray of angle θ which is in standard position. A student found the six trigonometric value
Delicious77 [7]

Answer:

The \sin \theta, \tan \theta, \csc \theta, \cot \theta 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 \sqrt{(- 7)^{2} + (- 24)^{2}} = 25.

If the point makes an angle \theta with the negative x-axis, then

\sin \theta = - \frac{24}{25}

\cos \theta = -\frac{7}{25}

\tan \theta = \frac{24}{7}

\sec \theta = - \frac{25}{7}

\csc \theta = - \frac{25}{24}

\cot \theta = \frac{7}{24}

Therefore, the \sin \theta, \tan \theta, \csc \theta, \cot \theta have the wrong values. (Answer)
