Question

I don’t get it I need hey

Answer 1

95° is your value for ∠n

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

Answer 2

n =95

Explanation:

The angles of a triangle add up to 180 degrees

55+ 30 +n = 180

Combine like terms

85+n = 180

Subtract 85 from each side

85-85 +n = 180 -85

n =95
