The sum of angles of a triangle is 180°, so m∠K = 180° -45° -30° = 105°.
The Law of Sines tells you
... FL/sin(∠K) = FK/sin(∠L)
Solving for FL, we get
... FL = FK·sin(∠K)/sin(∠L)
... FL = a·sin(105°)/sin(30°) = a·sin(105°)/(1/2)
... FL = 2a·sin(105°) ≈ 1.93185a
Answer:C
Step-by-step explanation:
Area = 1/2 b h

Answer:
47 stamps.
Step-by-step explanation:
If Leah bought 19 snowflake stamps, 24 truck stamps (19 + 5 = 24), and 4 rose stamps (24 - 20 = 4), the answer would come out to 47 stamps in total.
Equation: 19 + 24 + 4 = 47
