Question

Plz solve steps by step

Answer 1

HERE IS YOURS SOLUTION;

◆ ∠ ACS + ∠ CAQ = 180° 【 Angles on the same side of the transversal are supplementary 】

★ => ∠ CAQ = 80° ★

Now,

∠PAB = ∠ ABC = 70° 【 Alternate Angles 】

★ => ∠ABC = 70° ★

Now,


∠ PAB + ∠ BAC + ∠CAQ = 180° 【 Linear Pair 】

=> 70° + ∠BAC + 80° = 180°

★ => ∠BAC = 30° ★
