Find Angle 'A' If :

Find angle 'A' if :

योग

From the figure we have

sin A = `((10)/sqrt(2))/(10)`

sin A =`(1)/(sqrt(2)`

sin A = sin 45°

A = 45°

Find AD, if :

Find AD, if:

Find the length of AD.
Given: ∠ABC = 60^o.
∠DBC = 45^oand BC = 40 cm.

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.

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: AB.
