Name the right angles for the 3 triangles
1. < _ _ _
2. < _ _ _
3. < _ _ _

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.

step-by-step explanation:

if you was gonna solve for a, a is a   < -12

m∠a is 90°

m∠b is 40°
