Answer:
the sum of the interior angles of a triangle is always 180°
x = 12
Step-by-step explanation:
- the sum of the interior angles of a triangle is always 180°
2x + 11 + 70 + 75 = 180
2x = 180 - 11 - 70 - 75
2x = 24
x = 12
----------
check
75 + 70 + 11 + 2 * 12 = ( remember pemdas)
75 + 70 + 11 + 24 =
180°
the answer is good
