Find angle 'A' if:

Find angle 'A' if:

योग

From the figure we have,

tan A = `"Perpendicular"/"Base"`

tan A = `(10sqrt(3))/(10)`

tan A = `sqrt(3)`

tan A = tan 60°

∴ A = 60°

Find angle 'A' if :

In trapezium ABCD, as shown, AB // DC, AD = DC = BC = 20 cm and ∠ A = 60°. Find: length of AB

In trapezium ABCD, as shown, AB // DC, AD = DC = BC = 20 cm and A = 60^°. Find: distance between AB and DC.

Use the information given to find the length of AB.

In the given figure, AB and EC are parallel to each other. Sides AD and BC are 2 cm each and are perpendicular to AB.

Given that ∠ AED = 60° and ∠ ACD = 45°. Calculate: AE.

In right-angled triangle ABC; ∠B = 90°. Find the magnitude of angle A, if:
BC is `sqrt(3)` times of AB.

Find AB and BC, if:

Find PQ, if AB = 150 m, ∠P = 30° and ∠Q = 45°.
