Answer 1

☆ Hello Friend ☆

As shown in diagram Triangle ADC is an isosceles triangle
So Two angles that is Angle DAC and ADC are equal.
ACD+130°= 180°
ACD= 180°-130°
ACD= 50°

x+50°+50°= 180°
2x=180°-100°
x=80°
x= 80°

80°+ADC=180°
ADC= 180°-75°
= 100°

Similarly triangleADC is an isosceles triangle
x+x+100°= 180°
2x=80°
x=80/2 = 40°

Hooe it helps☺
