Answer 2

Answer:

Measure of ∠ABC is $88$° .

Step-by-step explanation:

To find : measure of ∠ABC .

Given :  ∠ABC + 68º =156º  

Solution :

• As per given data we know that sum of two angles is $156$° . One of the angle is $68$° . we have to find measure of second angle , ∠ABC .

        i.e. ∠ABC + $68$° = $156$°

• To find the angle ∠ABC , we transpose $68$° at RHS changing its sign to negative .

• ∠ABC $= 156 - 68$

                     $= 88$°
