Super easy question if ur looking for points :) 1 1/2 times 3

4.5

Step-by-step explanation:

1 1/2 as a fraction is 3/2 and you will put the whole number 3 as 3/1 and 3/2 times 3/1 and 3/2 times 3/1 is 9/2 which equals 4.5!

Hope this helps you!  :)

PLZ MARK ME AS BRAINLIEST! ( if u want to)

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.

0 is its x and y coordinate
