Answer:
137
Step-by-step explanation:
180-43=137
the 180 comes from when you combine angles 1 and 2 (because they form a straight line). you subtract angle 1 and you will get angle 2. since angle 2 and 4 are across from each other, that means they are the same degree. so the answer would be 137
615
4100*3 then you have to multiply by the rate in decimal form which is 0.05!
hope this help the other angles are 5 degrees, 175degrees and 175 degrees
