Question

What is the value of x? O 40 O 70 O 140 O 160

Answer 1

Answer:

70

Step-by-step explanation:

Because we know that a triangle always adds up to 180°, and this triangle has 2 congruent sides, it means that the angle of x must be itself multiplied by 2 from the remaining degrees needed to make 180°.

In this case: 2x° + 40° = 180°

x = 70°

Answer 2

The answer is 70 degrees
