What is the value of x?
040
O 70
O 140
O 160

x = 70

Step-by-step explanation:

base angles are congruent

40 + x + x = 180

40 + 2x = 180

-40            -40

2x = 140

2      2

x = 70

B. 70

Step-by-step explanation:

its an isosceles triangle so the two angles are congruent.

you already know that all triangles add up to 180

solve for x

40 + x + x = 180

40 + 2x = 180

2x = 140

x = 140/2

x = 70

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
