Can anybody me get the answer or me understand how to do this

51.3

Step-by-step explanation:

This is a right triangle (because of the 90° angle).  For any right triangle, you can use the following:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

You can remember this as SOH-CAH-TOA.

We want to find the angle y.  We know that the opposite side is 10 and the adjacent side is 8.  So we can use tangent:

tan y = 10 / 8

y ≈ 51.3°

what statement? is there an image?

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
