Find the value of 'A', if 2 cos A = 1

Sum

2 cos A = 1
⇒ cos A = `(1)/(2)`
⇒ cos A = cos60°
⇒ A = 60°.

From the given figure,
find:
(i) cos x°(ii) x°(iii) `(1)/(tan^2 xx°) – (1)/(sin^2xx°)`
(iv) Use tan x^o, to find the value of y.

Solve for x : sin (x + 10°) = `(1)/(2)`

Solve for x : 2 cos (3x − 15°) = 1

If θ < 90°, find the value of: `tan^2θ - (1)/cos^2θ`

Find:
a. BC
b. AD
c. AC

Find the value 'x', if:

Find x and y, in each of the following figure:

Evaluate the following: `(sin25° cos43°)/(sin47° cos 65°)`

If A + B = 90°, prove that `(tan"A" tan"B" + tan"A" cot"B")/(sin"A" sec"B") - (sin^2"B")/(cos^2"A")` = tan²A
