Question

Give the answer quickly with explanation ​

Answer 1

Answer:

very simply we can solve the question by using angle sum property of triangle

Step-by-step explanation:

in an isosceles triangle

opposite sides are equal

70+40+x=180

x=180-110

x=70

so, angle a= angle c

and hence opposite sides are also equal.

Answer 2

Answer:

here

<A+<B+<C=180[Sun of interior angle of a triangle]

Step-by-step explanation:

<A+<B+<C=180

or,70+40+<C=180

<C=70

HERE as two base angles of the triangle are equal so the two sides are also equal.so,as two sides are equal we can say that it is a isosceles triangle.
