Can someone me find the missing angle of the triangle in steps. if you

Step-by-step explanation:

All triangles have 180 degrees. There are no exceptions to that rule. You find an exception, you are finding something that can never be.

Call the missing angle x

51 + 73 + x = 180                  Add numbers on the left.

124 + x = 180                         Subtract 124 from both sides.

124-124 +x = 180 -124           The 124s on  the left cancel. The right = 56

x = 56

using pemdas, (order of operations) you'll see the answer is 24.
