Question

solve this sum.... maths​

Answer 1

here is your answer mate:

since AB = AC

it is an isosceles triangle with angle B = angle C

thus, angle A = 2x angle B = angle C = x + 10

according to the angle sum property of the triangle,

angle A + angle B + angle C = 180

angle A + 2 angle B = 180

2x + 2(x + 10) = 180

2x + 2x + 20 = 180

2(x + x + 10) = 180

x + x + 10 = 90

2x + 10 = 90

2x = 80

x = 40

therefore, angle A = 2x = 80 degrees

angle B = angle C = x + 10 = 50 degrees

hope this answer helps you buddy

please mark as brainliest:-)

Answer 2

Answer:

A=2x

B=x+10

C=x

2x+x+10=180

12x=180

x=180/12

x=15
