Answer:
x = 44°
Explanation:
Take the 90° as z and the interior angle near the exterior angle 134° as y.
Formula we use,
→ Exterior angle + Interior angle = 180°
Then the value of y will be,
→ 134° + y = 180°
→ y = 180° - 134°
→ [ y = 46° ]
We know that,
→ Sum of all interior angles of ∆ = 180°
The required value of x will be,
→ x + y + z = 180°
→ x + 46° + 90° = 180°
→ x + 136° = 180°
→ x = 180° - 136°
→ [ x = 44° ]
Hence, the value of x is 44°.
