Answer:
x = 80°
Explanation:
Given interior angles,
→ 60°
→ 40°
Now we have to,
→ Find the required value of x.
We know that,
→ Sum of interior angles in triangle is 180°.
Formula we use,
→ <A + <B + <C = 180°
Forming the equation,
→ x + 60° + 40° = 180°
Then the value of x will be,
→ x + 60° + 40° = 180°
→ x + 100° = 180°
→ x = 180° - 100°
→ [ x = 80° ]
Hence, the value of x is 80°.
