![T h e space l e n g t h space o f space t h e space s i d e space f r o m space w h i c h space t h e space a n g l e space i s space 45 to the power of 0 space i s space
tan 45 to the power of 0 equals 9 over y
y equals 9 m
T h e space l e n g t h space o f space t h e space s i d e space f r o m space w h i c h space t h e space a n g l e space i s space 30 to the power of 0 space i s
tan 30 to the power of 0 equals 9 over x
fraction numerator 1 over denominator square root of 3 end fraction equals 9 over x
x equals 9 square root of 3
A r e a space o f space t h e space f i e l d space equals x cross times y
