Question

pls tell the answer with working​

Answer 1

Part (i):

x = 50° {Opposite Angles of equal sides are equal}

Part (ii):

x + x = 110° {Exterior Angle Property}

2x = 110

x = 55°

Answer 2

Answer:

i) x=50°

ii) x=55°

Step-by-step explanation:

I) because x is opposite angle of 50°and opposite angles are equal.

therefore,x=50°

ii) angle 110+angleA=180°

therefore,angle A=180-110=70°

angle A+angle B+angle C=180°

therefore,70°+angle b+angle c=180°

because, opposite angles are equal;angle B=angle C

=>70°+2x=180°

=>2x=180°-70°

=>x=110÷2

=>x=55°
