Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = =
=
( multiply both sides by x )
11 = x ×
( divide both sides by
)
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11 )² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y = = 22
