Idk why i’m so stuck and i’m gonna regret wasting an ask on this but someone lmk how i get the answer! (the answer is 136 idk how to get there)

See the attached image. What you have so far is correct. You'll use the two parallel lines to use the alternate interior angle theorem. This is shown by the two red angles in the diagram. Based on that we know...

angle CRK = angle RCI = 44 degrees

Then you'll use the fact that triangle RCK is isosceles, so angle K is also 44 degrees

Afterward, use a bit of algebra to find angle RCK = 92 degrees. More specifically, you'll solve x+44+44 = 180 to get x = 92

Finally add up 44 and 92 to get 136 as the answer

The lateral side of a triangular pyramid is a triangle. in order to increase the lateral surface area, the slant height and the height should be altered

Iam thinking the answer is a.) knew
