Calculate the area of triangle CDE with altitude EF, given C (3,-2), D (-1, 2), E (2, 3), and F (0.1).

4 Square Units

6.2 Square Units

8 Square Units

8.7 Square Units

I think it is 8 square units, I am taking that test now xd

The answer is 8 square units.

Step-by-step explanation:

Hope this helps :)

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
