Answer:
d)13sin75/sin55
Step-by-step explanation:
1)Given
inΔVWU, ∠V= 75°
∠U= 50°
Finding ∠W:
∠W= 180-(75+50)
=180-(125)
= 55
Now finding x, using law of sine
x/sinV = 13/sinW
Putting the values in above we get:
x/sin75=13/sin55
Re-arranging, we get:
x= 13sin75/sin55 !

Answer:
C. 3/7 is not a reasonable answer for the fraction of his birthday money Matthew has spent. The fraction should be closer to 1.
Step-by-step explanation:
Let's say c is the price of cinnamon tea, and s is the price of spice tea.
10c + 2s = 13
16c + 8s = 28
Divide the second equation by 4:
4c + 2s = 7
Subtract from the first equation:
6c = 6
c = 1
Use any equation to find s.
s = 1.5
Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.
