Answer:
A
Step-by-step explanation:

First of all, let’s find CB.
sin(45°) = CB : 6sqrt(2)
CB = 6
Now we can find CD
cos(60°) = x : 6
x = 3
Add 1/3 on both sides
a= 1
Least common multiple is like 10 and 20 where they can both be divided by 10, and 5 but the least common multiple is 5. Whereas least common denominator is like 4/8, 8 is a denominator but not the LEAST the least would be 1/2.
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
2x = 8 ( divide both sides by 2 )
x = 4
