Answer:
51°
Step-by-step explanation:
Note that the square in the angle place = 90°.
Also note, that a complete circle is 360°.
Set the equation. Let the ? be denoted by the variable x:
x + 90+ 124 + 95 = 360
Simplify. Combine like terms:
x + (90 + 124 + 95) = 360
x + (309) = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:
x + 309 (-309) = 360 (-309)
x = 360 - 309
x = 51
51° is your answer.
