The answer is 143 because angles 1 and 3 are supposed to be 180 and since 2 and 4 are 37 degrees you just have to do 180-37 and you get 143

< is angle

For the first one, <2+<3 equals 180

So, 37+<3=180. Rewrite that, and <3=180-37, which then <3 is 143 degrees

For the second one, COMPLEMENTARY ANGLES ADD UP TO 90 DEGREES

So, if one angle is 35 degrees, and we rewrite that again, 90-35 is it's complement.

So the answer to the second one is 90-35, 55.

I hope this is helpful
