If the angles are of equal measure, then the measure of the angles be x and x respectively.
Then,
x+x=180
⇒ 2x=180
⇒ x=90

Let x be the angle.
Given, supplement of angle x is 65o
=> x+65o=180o
x=115o
But the complement of the angle 115o degrees cannot be determined. Because of the pair of angles whose sum is 90° is called complementary angles.

Linear pair of angles must add upto 180°.
If one of the angle forming a linear pair is right angle (90°).
The other angle would obviously be 90°.
As it would add upto 180.

(i) No. Acute angle is always lesser than 90º. It can be observed that two angles, even of 89º, cannot add up to 180º. Therefore, two acute angles cannot be in a supplementary angle pair.

Let the x be the measure of the two angles which are supplementary.
x+x=180o
2x=180o
x=90o
∴ measure of an each angle = 90o

The sum of the measures of two supplementary angles is 180°.
Let the measuare of angle is x
x + 135° = 180°
x = 180° - 135°
x = 45°
∴ The measure of the supplement of an angle of 135° is 45°.

-7/12+(-2/13)
= -7/12 -2/13
= [-7(13) - 2(12)]/156
= (-91 - 24)/156
= -115/156

-6/13-(-7/15)
= -6/13 + 7/15
= [-6(15) + 7(13)]/195
= -90 + 91
= 1

Find the cost of 1 pen:
12 pens = Rs 40
1 pen = 40 ÷ 12 = Rs 10/3
Find the selling price of 1 pen:
8 pens = Rs 24
1 pen = 24 ÷ 8 = Rs 3
Find the profit / loss :
Cost Price > Selling Price ⇒ It is a loss
Loss = 10/3 - 3 = Rs 1/3
Find the loss percentage:
Loss percentage = (1/3 ÷ 10/3) x 100
Loss percentage = 10%
Answer: The loss is 10%

An altitude of a triangle is a line segment that starts from the vertex and meets the opposite side at right angles.
A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex.
