Question

in the given figure,∆ABC is an Isosceles Triangle with AC=BC and angle A =70°.Find the value of x. ​

Answer 1

Answer:

Explanation:

Ac=bc=e(isoceles traingle)

e+e+70°=180°(angle sum property of traingle)

2e+70°=180°

2e=180-70

2e=110°

e=110/2

e=55°

x=b+a(exterior angle property of traingles)

x=55°+70°

x=125°

Answer 2

Answer:

here AB = AC.... ( isosceles triangle)

therefore B = C

Step-by-step explanation:

sum of measure of angles of triangle is 180

so,

A+B+C=180

70+2B= 180

2B = 180-70

B= 110/2

B= C = 55

x = A+B

x= 70 +55

x= 125
