Answer:
∠ABC= 82°
∠ACB= 82°
∠BAC= 16°
Step-by-step explanation:
∠ABC +∠ACB +∠BAC = 180° (∠ sum of △ABC)
(5x -3)° +(5x -3)° +(x -1)°= 180°
5x -3 +5x -3 +x -1= 180
11x -7= 180 <em>(</em><em>simplify</em><em>)</em>
11x= 180 +7 <em>(</em><em>+</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
11x= 187
x= 187 ÷11
x= 17
∠ABC
= (5x -3)°
= [5(17) -3]°
= 82°
∠ACB
= ∠ABC
= 82°
∠BAC
= (17 -1)°
= 16°
Alternatively,
∠BAC
= 180° -82° -82°
= 16°
