Question

please answer with explanation

Answer 1

as AB = AC

it is an isosceles triangle

angle B + angle C = angle A (outer angle)

as in iscoles triangle angles opposite to equal sides are equal

that means angle B = angle C

which means 110/2 = angle C = angle B

angle C = angle B = 45 degree

using angle sum property we can find the third angle

angle A + angle B + angle C = 180

angle A + 45 + 45 = 180

angle A + 90 = 180

angle A = 90

Answer 2

Answer:110+x=180

X=70

Step-by-step explanation:angle A is 70 coz there is linear pair

So as Angle A=70

Similarly let angle B and C be x

So 70+x+x=180,as sum of traingle is 180

70+2x=180

2x=180-70

2x=110

X=110/2

X=55

Therefore angleA=70, B=55,C=55

70+55+55=180
