Answer:
[tex]y=39\degree[/tex]
Step-by-step explanation:
The given triangle is a right angle triangle .
The known sides of the triangle that is opposite to angle y is 8 units while the side adjacent is 10 units.
The value of y can be calculated using the tangent ratio.
[tex] \tan(y)=\frac{8}{10}[/tex]
We solve for y to get,
[tex]y=arctan(\frac{4}{5})[/tex]
We evaluate to obtain,
[tex]y=38.66[/tex]
[tex]y=39\degree[/tex] to the nearest degree
