Answer:

Step-by-step explanation:
Multiply the fraction by the conjugate and solve (would explain more but you're on a time crunch)
Sin(x)=40/50
x= sin^-1(40/50)
x= 53.1301023542—>53.1 rounded to the nearest tenth
angle of elevation is 53.1
Answer:
$3.49 for the muffin, and $2.96 for the coffee
Step-by-step explanation:
(3.25)(1.075) = 3.49
