Question

In the following questions,the measures of two angles are given.In each case find the measure of the third angle:. 1.30,80. 2.40,40. 3.20,70. 4.59,45.​

Answer 1

Step-by-step explanation:

As, angle a + angle b + angle c= 180;angle sum property of triangle

To find:

c= 180-(a+b)

In 1:

Two angles are a=30 and b=80

c= 180-(a+b)

= 180-(30+80)

= 180-110

= 70

In 2:

Two angles are a=40 and b=40

c= 180-(a+b)

= 180-(40+40)

= 180-80

= 100

In 3:

Two angles are a=20 and b=70

c= 180-(a+b)

= 180-(20+70)

= 180-90

= 90

In 4:

Two angles are a=59 and b=45

c= 180-(a+b)

= 180-(59+45)

= 180-104

= 76
