Well i'm not sure what that is, and also, 2+i seems to be wrong.

angle a + angle b + angle c = 180 because the 3 interior angles of a triangle add to 180.

now, angle a is 40 degrees, because the 40 degree angle and angle a are corresponding angles (parallel lines and transversals).

The triangle is isosceles, so angle a = angle c. Angle c is 40 degrees, and by corresponding angles, the supplement of angle e is 40 degrees.

180-40=140

angle e is 140 degrees

180+140=320

The answer is 320. Sorry if it isn't really well explained, I'm not the best at explaining things.

Edit: 5 seconds after posting, i realize i said 220 instead of 320. Simple math mistake!

Don't worry about it, the same here!

I would think that if I had more time, I would've done better.

(3/6)^2+7*4-5

9/36+7*4-5

1/4+28-5

1/4+23

23 1/4

This is all very true!

Here is something to look at!

physics does have a lot of math involved in it, right?
