Collisions problem completed - is it correct?

[Hemingway]

Hello - I am pretty sure this is correct but there is no answer for me to check. My friend (who is a lot smarter than me :P ) got a different answer entirely. Is the following answers correct?

Homework Statement

Puck A has a mass of 0.0300 kg and is moving along the x-axis with a velocity of +4.20 m/s. It makes a collision with puck B, which has a mass of 0.0600 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B.

puck a is 65 degrees above x axis
puck b is 37 degrees below the x axis

The Attempt at a Solution

(0.0300) (4.2) + 0 = (0.0300) (V_A COS 65) + .0600 (V_B COS 37)
0.126 = 0.0127 V_A + 0.0479V_B

0 = 0.0300 (V_A SIN 65) + (0.0600)(-V_BSIN 37)
= 0.0272 V_A + -0.0361 V_B
0.0361V_B = 0.0272V_A
V_B = 0.0272VA/0.0361
VB = 0.753 VA

0.126 = 0.0127 VA + 0.0479VB
0.126 = 0.0127 VA + (0.0479)(0.753)
0.126 = 0.0127 VA + 0.0361 VA
0.126 = 0.0488 VA
VA = 0.126/10.0488
VA = 2.58 m/s

VB = 2.58 m/s x 0.753
= 1.94m/s
