see the attached figure
75°=mAC/2-------------------- > mAC=75°*2=150
the answer is 150
Answer:
I am confused what is the question?
Answer:
4 x 3
Step-by-step explanation:
The order of a matrix is given by stating the number of rows followed by the number of columns.
The matrix here has 4 rows and 3 columns thus order is
4 x 3
The answers are as follows:
1-D
2-B
3-C
4-A
Thus L.H.S = R.H.S that is 2/√3cosx + sinx = sec(Π/6-x) is proved
We have to prove that
2/√3cosx + sinx = sec(Π/6-x)
To prove this we will solve the right-hand side of the equation which is
R.H.S = sec(Π/6-x)
= 1/cos(Π/6-x)
[As secƟ = 1/cosƟ)
= 1/[cos Π/6cosx + sin Π/6sinx]
[As cos (X-Y) = cosXcosY + sinXsinY , which is a trigonometry identity where X = Π/6 and Y = x]
= 1/[√3/2cosx + 1/2sinx]
= 1/(√3cosx + sinx]/2
= 2/√3cosx + sinx
R.H.S = L.H.S
Hence 2/√3cosx + sinx = sec(Π/6-x) is proved
