<em>Answer:</em>
<em>∠x = 70°</em>
<em>Step-by-step explanation:</em>
<em>Given that PQ||BR</em>
<em>Line PQ and BR with transversal AC,</em>
<em>∠x + ∠ACR = 180° {Co-interior angles}</em>
<em>⇒∠x + 110° = 180° {From what I can see it looks like 110.}</em>
<em>⇒∠x = 180° - 110°</em>
<em>⇒</em><em>∠x = 70°</em>
