PLS HELP<3ty this is due today! so please helppp tysmmm and have a great night or morning! :) (spam)

so u need to measure it  with a ruler

Step-by-step explanation:

ok so meausre each side

then if all the sides have the same length, then it is a equilateral triangle

if only two of the sides are equal, then it is isoceles

and if all the sides have different lengths, then it is scalene

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
