Answer:
107°
Step-by-step explanation:
By definition of a triangle, the ∑ of all angles within the triangle = 180°
It is given that two angles measurements are 44 and 29. Set the equation:
180 = 44 + 29 + x
First, simplify. Combine like terms:
180 = (44 + 29) + x
180 = x + 73
Next, isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other. Subtract 73 from both sides of the equation:
180 (-73) = x + 73 (-73)
x = 180 - 73
Subtract:
x = 180 - 73
x = 107
x = 107° is your answer.
