Question

if two interior angles is a triangle sum 135° then third angle is equal to​

Answer 1

Step-by-step explanation:

the angles of a triangle add upto 180

180-135=45

Answer 2

Answer :

• Third angle is 45⁰

Given :

• Two interior angles is a triangle is 135⁰

To find :

• Third angle

Solution :

• Let the third angle bs x

As we know that ,

• Sum of all angles in a triangle is equal to 180⁰

And also Given that,

• Sum = 135⁰

》x + 135⁰ = 180⁰

》x = 180⁰ - 135⁰

》x = 45⁰

Hence , Third angle is 45⁰

Verification :

As we know that,

• Sum of all angles in a triangle is 180⁰

Given that , third angle is 45⁰

》180⁰ - 45⁰

》135⁰

Hence Verified
