Answer:

∠ DCF = 39°

Step-by-step explanation:

the secant- secant angle DCF is half the difference of the measures of the intercepted arcs, that is

∠ DCF = \frac{1}{2} (EG - DF) = \frac{1}{2} (127 - 49)° = \frac{1}{2} × 78° = 39°

The coordinates of three vertices of a triangle are (3, 5), (-1, 5), and (-1, -3). What is the area of the triangle?

If you would graph the triangle, one of the legs would be 8 and another would be 5 and the area of a triangle is bxh/2 so the equation is 8x5/2=20un².
