Question

in triangle ABC , AB = AC , √a= 70 find √c ​

Answer 1

Answer:

since, ab = ac

triangle ABC is isosceles.

so, if angle a = 70 then, angle b = 70 (corresponding sides are equal and corresponding angles are equal)

so,a+b+c=180

70 + 70 + x = 180( sum of all angles)

140 + x = 180

x = 180 - 140

x = 40

therefore angle a equals 40 degrees
