x = 3
Hope this helps!
Step-by-step explanation:
ΔABC is a 45°, 45°, 90° triangle. The longest side ( 6 ) can be
while AB and CB are x. Because 6
is equal to
, you can see that x is equal to 6. Both AB and CB are equal to 6. ΔBDC ( CDB ) is a right triangle ( 30°, 60°, 90° ) so, BD = x, CB = 2x, and CD =
. CB is equal to 6 so 2x = 6, x = 3.
Evaluate the trigonometric expression using sum and difference formulas.
