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
