उत्तर
BEDC is a rectangle.
⇒ BE
= DC
= `60sqrt(3)"m"`
In right ΔAEB,
tan30° = `"AE"/"BE"`
⇒ `(1)/sqrt(3) = "AE"/(60sqrt(3)`
⇒ AE = 60m
Now,
x = AD = AE + ED
= 60 + 15
= 75m.

If 2 sin x° − 1 = 0 and x° is an acute angle; find:
- sin x°
- x°
- cos x° and tan x°.
From the given figure,
find:
(i) cos x°
(ii) x°
(iii) `(1)/(tan^2 xx°) – (1)/(sin^2xx°)`
(iv) Use tan xo, to find the value of y.
Use the given figure to find:
(i) tan θ°
(ii) θ°
(iii) sin2θ° - cos2θ°
(iv) Use sin θ° to find the value of x.
Solve for x : 2 cos (3x − 15°) = 1
If A = 30°, verify that cos2θ = `(1 - tan^2 θ)/(1 + tan^2 θ)` = cos4θ - sin4θ = 2cos2θ - 1 - 2sin2θ
If A = B = 60°, verify that: tan(A - B) = `(tan"A" - tan"B")/(1 + tan"A" tan"B"")`
Find the value of: `sqrt((1 - sin^2 60°)/(1 + sin^2 60°)` If 3 tan2θ - 1 = 0, find the value
a. cosθ
b. sinθ
Evaluate the following: `(sin25° cos43°)/(sin47° cos 65°)`
Evaluate the following: sin28° sec62° + tan49° tan41°
Evaluate the following: `(3sin^2 40°)/(4cos^2 50°) - ("cosec"^2 28°)/(4sec^2 62°) + (cos10° cos25° cos45° "cosec"80°)/(2sin15° sin25° sin45° sin65° sec75°)`
