Question

slove it and explain me perfectly​

Answer 1

Answer:

In the above figure,

AB=AC(Given)

=> /_ACB = /_ABC(Angles opposite to the equal sides are equal)

=> x = 70°

The other answer given is wrong!

Answer 2

Answer:

40

Step-by-step explanation:

Please read this carefullly.

There is an isosceles triangle shown in the figure. Opposite sides pr the sides which have lines on them are congruent, means are if same measurement. According to this, the bottom two anglesn or the angles joining from the base to both heights are also congruent. So, as measure of angle ABC is 70° then measure then the measure of angle ACB will be 70°. As measure of all angles of a triangle is 180° and two of them measure 70°,

we can say,

180° = 70° + 70° + x

= 180° = 140° + x

So,

x = 180° - 140°

= x = 40°
