Answer:
Both Law of Sines and Cosines can be used to determine the angle Q.
Step-by-step explanation:.
Since from Law of Sines with one angle and three sides we can find other angles using the ratio obtained with the given angle and side length opposite side if angle P is not given we couldn't use this.
Law of Cosines can be used to find any angle of triangle with all three side lengths given and angle P is also not required to find angle Q.
Answer:
Each eraser costs $2.00
Step-by-step explanation:
<u>Step 1: Make an equation</u>
4 + 5a = 14
4 = shows that cost for one magazine
5a = shows that 5 erasers cost a each
14 = total price
<u>Step 2: Solve for a</u>
Subtract 4 from both sides: 4 + 5a - 4 = 14 - 4
Divide by 5 from both sides: 5a / 5 = 10 / 5
Answer: a = 2
