​Find the area of the right triangle △DEF with the points D (0, 0), E (1, 1), and F.
m∠
DEF = 60°
.

A	√3
B	√6
C	√2
D	√3 ​ √2 ​

Can anyone do this ??

This is the fourth question you have posted indicated that you are "confused". Do you not know the meanings of any of the words used? If, as you seem to be implying, you have never taken a geometry or trigonometry course, where are you getting these problems? Do you know how to find the length of the hypotenuse of this triangle? Do you know what the sine of 60 degrees is? Do you know how "sine" is defined? Do you know how to find the area of a right triangle?

If you haven't actually studied this material yet, then you need to take the appropriate course(s). Us giving you the answers to practice tests (besides being unethical) does nobody any good. Sorry.
