id21 · Answer

because a and m are equal (equal angles)

In the figure below, USV is a right triangle. Which is the value of VW? 
 
Answer    36 
   21 
   15 
   16

id21 · Answer

36

id21 · Answer

$$\sqrt{39^2-15^2}=36$$

anonymous · Answer

it cant be because i put that and my teacher said is was wrong

id21 · Answer

But if USW is right triangle, you can use $$c^2=a^2+b^2$$, where c is the hypotenuse and a and b are two other sides

anonymous · Answer

ikr same thing i tld her but she said that isnt right

anonymous · Answer

VS = 36
VW = 36 - 15 = 21

id21 · Answer

Oh, yes, LA-MeC right. VS=36, but you must find VW.  SW is known as 15, as a radius.
