In `triangle ABC` ,if `B=45^(0),C=120^(0),a=40cm` ,the length of the perpendicular from A on BC produced is

ABC is an isosceles triangle with AB = AC =13 cm and BC = 10 cm. Calculate the length of the perpendicular from A to BC.

If in Delta ABC, b = 3 cm, c = 4 cm and the length of the perpendicular from A to the side BC is 2 cm, then how many such triangle are possible ?

ABC is a triangle in which AB = AC = 4 cm and angleA=90^(@) . Calculate: the length of perpendicular from A to BC.

The point A(0, 0), B(1, 7), C(5, 1) are the vertices of a triangle. Find the length of the perpendicular from A to BC and hence the area of the DeltaABC .

Using ruler and compasses only construct a triangle ABC in which BC = 4 cm. angleACB = 45^(@) and perpendicular from A on BC is 2.5 cm. Draw a circle circumscribing the triangle ABC

In the given figure, DeltaABC ~ Delta ADE . If AE : EC = 4:7 and DE = 6.6 cm , find BC. If *x' be the length of the perpendicular from A to DE, find the length of perpendicular from A to BC in terms of ‘x'.

If the hypotenuse of a right-angled triangle is four times the length of the perpendicular drawn from the opposite vertex to it, then the difference of the two acute angles will be 60^0 (b) 15^0 (c) 75^0 (d) 30^0
