    I am thinking we can solve this with Cosine Law and maybe Sine Law

    You want to use the law of sines. \[\frac{\sin(A)}{A} = \frac{\sin(B)}{B}\]

    A = 24, angle A = 67.38 B = 26, angle B = X

    \[ \frac{\sin 67.38}{24} = \frac{\sin B}{26}\] \[ \frac{26\times\sin 67.38}{24} \]

    no, you want to rearrange the equation to find X. \[\sin(X) = 26 \cdot \frac{\sin(67.38)}{24}\]

    At 90 degrees sine is (0,1) and cosine is (1,0)
