Answer» In △ABC AB=AC⇒∠B=∠C (Angles opposite to equal SIDES are equal)Now using ANGLE sum property∠A+∠B+∠C=180 ∘ ⇒80 ∘ +∠C+∠C=180 ∘ ⇒2∠C=180 ∘ −80 ∘ ⇒∠C= 2100 ∘ =50 ∘ now ∠C+∠x=180 ∘ (Angles made on straight line (AC) are supplementary)⇒50 ∘ +∠x=180 ∘ ⇒∠x=180 ∘ −50 ∘ =130 ∘@ARSH[email PROTECTED]_arsh_deep_29 |
