Answer:
237/28
Step-by-step explanation:
4 5/7=33/7
3 3/4=15/4
----------------
33/7+15/4=132/28+105/28=237/28
14,18 and 22 is already an even number
Answer:
12
Step-by-step explanation:
Assume that those angles' curve in the triangle have same measure.
Law of Sin states that:
From the question, assume that B and C are congruent or have same measure. Let B and C be congruent; angle B = angle C thus:-
Let b = x and c = 12; for angle B, it's not given so leave it.
Multiply both sides by LCM which is 12x.
Divide both sides by sinB.
Therefore, x = 12.
Answer : C
i.e. f(x) =12 when x = 9
Explanation :
Since we have given that
x=9 lies in the interval [9,13]
so f(x) will be 12 for x=9
in another interval i.e (-6,9)
x can't be 9 as it is an open interval which does not include 9 .
so we'll go for f(x)=12 when x=9.
