Question

one of the angle of a triangle is 100° and the other two numbers are equal . find each of the equal angles​

Answer 1

Answer:

plz mark me as the brainliest

Step-by-step explanation:

Let the angles be x.

Now, Using angle sum property

a+b+c= 180

100+x+x= 180

2x=180-100

2x= 80

x= 80/2

x= 40

REQUIRED EQUAL ANGLES IS 40°

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Let the three angles be a,b and c

it is given that angle a = 100°

we know that, sum of angles of a triangle is 180°

angle b = angle c

hence, a + b + c =180

100° + b + b = 180°.... ( angle b = angle c)

2b = 180 - 100

2b= 80

b = 80/2

b = 40°

it is given that angle b = angle c

therefore angle is also equal to 40°

hence,

The other two angles are 40° each.
