If the bottom side is 20 cm, then each line BE and CE would each be 10 cm.
Now, just focus on the top left triangle. You have one side with 20 cm, and the other side with 10 cm. You are left with the hypotenuse, which you need to figure out the value of.
Since this is a right triangle, you can use the Pythagorean theorem -> a^2 + b^2 = c^2 where c is the hypotenuse.
20^2 + 10^2 = c^2
400 + 100 = c^2
500 = c^2
22.36 = c

Answer: 90 degrees
Step-by-step explanation:
Same-side interior angles thm states that the 90 deg angle and angle 3 are supplementary.
Shifting a graph down by 5 units is the same as subtracting 5 from the right side. So, k is 5.
