What you say makes no sense.

The problem is LITERALLY unsolvable if we can't assume that all the lines are straight.

The schematic was OF COURSE purposefully drawn in a way to make the viewer assume that the third angle of the left triangle is 90°, making the angle to it's right also be 90°, but the point of the exercise is to get the student to use ALL the given information instead of presuming right angles.

And NO, assuming all the lines are straight is NOT unreasonable, it is the only way that the problem could ever possibly have a solution.

Unless there are lines that are not straight in the image (which would make the calculation of x literally impossible), the third angle of the triangle in the left has to be 80°, making the angle to its right to be 100°, making the angle above it to be 45°, making the angle above it to be 135°. This is basic trigonometry.

We will probably be underwater in 2030.

I think that I should become a captain in a supertanker...

"- Setting the clock and a timer to record something on your VCR"

You just awakened a sad memory from 30 years ago... I wanted to record a movie I saw in the TV programme magazine but it started after midnight and I should have used the next day's date :-(

"Just use the keyboard!"

This is some Black Mirror shit right here.

"We do not talk about it!"

Aren't centrist voters mainly going to vote for Biden? Aren't leftist voters the ones threatening not to vote Biden because he is too far too the right from their perspective?
