It would be 5 more than half of a number.
Answer:
option C is correct answer ..
Step-by-step explanation:
angle A + angle B + angle C = 180° ( by angle sum property of triangle )
3x + 4x-19+ 3x -1 = 180
10x + -20 = 180
10x = 180 +20 = 200
x = 200/10 = 20 °
angle A = 3× 20 = 60 °
angle B = 4× 20 - 1 9 = 61 °
angle C = 3× 20 -1 = 59 °
angle B is greatest so side opposite to it will be greatest in length ....so length of AC is greatest ....
so option C is the correct answer of this question ...
plz mark my answer as brainlist plzzzz vote me also as I have done this question by taking a lot of time Hope it will be helpful for you ....
The underlying arithmetic progression is
-15, 0, 15, 30, ...
starting with 
and with a common difference of 
between terms. Recursively, this sequence is given by
So we have
and so on, so that the explicit rule for the sequence is
for 
.
The series consists of 15 terms, since
So we have
and the answer would be B.
