Answer:
12.56
Step-by-step explanation:
4 ×3.14 to get 12.56
Answer:
The equation is:
An identity
Has infinitely many solutions
No solution
Step-by-step explanation:
Because there is integers on both sides, we know that any attempts to fix this will either cause an identity, or a false numerical equation(an identity but <em>w r o n g</em>).(Note, an identity can either mean 2 = 2 or x = x).
Identities have infinite solutions, because it does not matter what you put in, the equation will always be true. False equations do not have a solution because they aren't even true equations.
Hope this helps!
x = 51.98
Step-by-step explanation:
tan 68 = opp/hyp = x/21
or
x = 21×tan68°
= 21(2.475)
= 51.98
