To solve this one, subtract 50 from 180 and you'll have your answer.
180 - 130 = 50
45+85=180 130=180 -130 -130 ________ The third angle is 50 degrees.

768 - (235 + 180) = 768 - 415 = 353
To solve this one, subtract 50 from 180 and you'll have your answer.
180 - 130 = 50
130/180 = 0.7222 repeating.

45+85=180 130=180 -130 -130 ________ The third angle is 50 degrees.
130
To find the answer, subtract 180 - 39. 39 + 141 = 180.
Well, 40 degrees is already given.. And the angle "R" I assume has a box in its corner, that represents a 90 degree angle. as for I.E: "L" <-- is a 90 degree angle. so you add 40 + 90 = 130. In all triangles will always = 180 degrees. No if and's or but's about it. so you would take your 130 degrees subtract from 180 degrees, 130 - 180 = 50! and that will decipher your answer your looking for.
180 - 90 is 90
