1.	In Fig. 8.5. AABC is isosceles with AB = AC. Find the values of Xandy
Answer» We know that the sum of the interior angles of a triangle is 180 °.then, A+B+C=180° A+B+30°=180°A+B=150°so, A=B=75° (Given, A=B)find the value of x and y ,x=180°-75°=105° ....( from external Angle.) y=180°-75°=105° Hence, x=y=105°

We know that the sum of the interior angles of a triangle is 180 °.then, A+B+C=180° A+B+30°=180°A+B=150°so, A=B=75° (Given, A=B)find the value of x and y ,x=180°-75°=105° ....( from external Angle.) y=180°-75°=105°

Hence, x=y=105°
