TRIGONOMETRY - Class 10 Maths MCQs

The line drawn from the eye of an observer to the point
in the object viewed by the observer is known as

Choose one:

	horizontal line
	vertical line
	line of sight
	transversal line

When we raise our head to look at the object, the angle
formed by the line of sight with the horizontal is known
as

Choose one:

	acute angle
	angle of elevation
	angle of depression
	right angle

Two poles are 25 m and 15 m high and the line joining
their tops makes an angle of 45

Choose one:

	5 m
	8 m
	9 m
	10 m

The angle of elevation of the top of a tower from a point 20 metres away from its base is 45

Choose one:

	10 m
	20 m
	30 m
	20 √ 3

The tops of two poles of height 20 m and 14 m are
connected by a wire. If the wire makes an angle of 30"
with the horizontal, then the length of the wire is

Choose one:

	8 m
	10 m
	12 m
	14 m

The angle of elevation of the top of a 15 m high tower at
a point 15 m away from the base of the tower is

Choose one:

	30
	60
	45
	75

When we lower our head to look at the object, the angle
formed by the line of sight with the horizontal is known as

Choose one:

	obtuse angle
	angle of elevation
	angle of depression
	acute angle

If two towers of height h] and h2 subtend angles of 60:
and 30

Choose one:

	1: 2
	1: 3
	2:1
	3:1

When a point is observed, the angle formed by the line of sight with the horizontal where the point being viewed is above the horizontal level is known as

Choose one:

	angle of elevation
	angle of depression
	angle of a triangle
	right angle

A person standing on the bank of a river find that the
angle of elevation of the top of a tower on the opposite
bank is 45

Choose one:

	breadth of the river is twice the height of the tower.
	breadth of the river is half of the height of the tower.
	breadth of the river is equal to the height of the tower.
	none of these.
