Answer:
95° is your value for ∠n
Step-by-step explanation:
Note that a triangle's total angle measurement is 180°. Solve, add all the angles together and set it equal to 180
n + 55 + 30 = 180
Simplify. Combine like terms:
n + 85 = 180
Isolate the variable (n). Note the equal sign, what you do to one side, you do to the other. Subtract 85 from both sides
n + 85 (-85) = 180 (-85)
n = 180 - 85
n = 95
95° is your value for ∠n
