Answer 1

Answer:

if we assume a triangle ABC

Step-by-step explanation:

then it is given that verrical angle is 100degree

so let A be 100 degree

in isosceles tri the other two angles are same side

angle A + angle B + angle C = 180 ( by angle property of triangle )

100 + B + C = 180

B+C = 80

2B = 80 ( B= C )

B = 40

so of coarse C will be 40

i hope this helps you

Answer 2

Answer:

The base angles are 40°

Step-by-step explanation:

we know that, in isosceles triangle two angles are equal .

Therefore, let the base angles be x

we know that, sum of angles in triangle is 180

x+x+100 =180°

=> 2x = 180-100

=>2x =80

=>x =40°

Hence, the base angles are 40°
