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:
Unitary cost (per pound)= $0.682
Step-by-step explanation:
Giving the following information:
Total cost= $3.75
Total pounds= 5.5 pounds
<u>To calculate the unitary cost of each pound, we need to use the following formula:</u>
Unitary cost= total cost / total pounds
Unitary cost per pound= 3.75 / 5.5
Unitary cost per pound= $0.682
they answer if he reads 29 each day on thurs. and fri. because if you add 27+31+28= 86 so you subtract 144-86=58 and divide 52/2 and get 29
