Question

plz give the ans fast​

Answer 1

Ans A = Sum of two interior angle = exterior angle

70°+50°+x=180

120+x=180

x=180-120

x60°

AnsB. Exterior angle = interior angle

70+x+100=180

170+x=180

x=180-170

x=10°

AnsC. Sum of all angles

x+x+x=180

3x=180

x=180/3

x60°

Answer 2

Answer:

I don't know the ans for q1 but I will help in q2.

Q2. For a and b part of the qn, we are going to use Exterior Angle Property. EAP states that an Exterior Angle of a triangle is equal to the sum of the opposite interior Angles.

Now,

a) x= 50°+70°= 120° (EAP)

b) 70°+x=100°

x=100°-70°

x=30°

c) x+x+x= 180°

3x=180°

x=180°÷3

x= 60°

I am sorry that I don't know qn.1
