9(2k+3)+2=11(k-y)
18k + 27 + 2 = 11k - 11y
18k + 29 = 11k - 11y
18k - 11k + 29 = 11k - 11y - 11k
7k + 29 = -11y
7k + 29 - 29 = -11y - 29
7k = -11y - 29
7k / 7 = -11/7y - 29/7
K = -11/7y - 29/7
The value of x is 21√2/2
The correct option is (A)
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
In triangle having angle 60.
sin 60 = P/ 7√3
√3/2= P/7√3
2P= 21
P= 21/2
Now again
cos 45= 21/2/x
1/√2 = 10.5/x
x= 21√2/2
