The calculated value of y in the right triangle is 8.10

How to determine the value of y

from the question, we have the following parameters that can be used in our computation:

The right triangle

The value of c can be calculated using the following tangent ratio

tan(51) = opposite/adjacent

Substitute the known values into the equation

tan(51) = 10/y

So, we have

y = 10/tan(51)

Evaluate

y = 8.10

Hence, the value of y is 8.10
