Question

Someone plzzz help me wit question

Answer 1

x = 70

Explanation:

To find the value of x we need to

we know that the figure is an isosceles triangle so the base angles will be equal

we also know that angle sum of triangle is 180

so

40 + x + x = 180

40 + 2x = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70
