Answer:
The sum of the measures of the angles in a triangle is equal to 180 degree.
In triangle FGH;
or
Substitute the given values from the given figure we have;
Simplify:
Given that:
Using Cosine ratio:
In a given figure:
Base = GH = x and Hypotenuse = FH = y = 80 cm
Then;
or
cm
Therefore, the value of :
x = 43.57 cm
y = 80 cm
