Answer 1

Answer:

The marked angle GEF is 25

Step-by-step explanation:

Here, we want to calculate the value of the marked angle

Mathematically, a diagram should do justice to this

Please check the attachment for the diagram

The theorem we want to use is that the sum of opposite interior angles equals the exterior angle

Thus, mathematically;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

The angle marked GEF is x + 19

That will be 6 + 19 = 25
