Answer:
A
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180
x = 180° - (90 + 16)° = 180° - 106° = 74° → A
the sum of the interior angles of a triangle is 180°, you have a 90° angle and a 16° angle, take away the know angles from 180°
180 - 90 - 16 =
74°
----------------
check
90 + 16 + 74 = 180°
the answer is good
