Answer:
Step 4
Step-by-step explanation:
Given: Steps used by Shelly to evaluate the expression
To find: step that includes Shelly's mistake
Solution:
According to PEMDAS,
P denotes Parentheses
E denotes Exponents
M denotes Multiplication
D denotes Division
A denotes Addition
S denotes subtraction
Step 3 is
and step 4 is 
In step 4, first subtraction operation has been applied before the division operation.

Answer:
x=21.35764429=21.4
Step-by-step explanation:
Take SOHCAHTOA
in this problem you're going to use SOH, which is sine= opposite/hypotenuse
sin31=11/x
Multiply by x as a way to isolate it
x(sin31)=11
divide my sin31 to isolate x
x=11/sin31
x=21.35764429
Answer:
