Question

What is the value of x?

Answer 1

Answer:

x = 23

Step-by-step explanation:

Seeing same-side exterior angles theoreom,

both of these angles add up to 180°.

Looking at this,

3x + (4x+19) = 180

3x + 4x + 19 = 180

Subtracting both sides by 19 to get x on the LHS:

3x + 4x + 19 - 19 = 180 - 19

7x = 161

x = 23
