The correct answer is B. 87°
Step-by-step explanation:
Let's recall that the interior angles of a triangle add up to 180°,
therefore, we have:
∠x + 28 + 65 = 180
∠x = 180 - 65 -28
∠x = 180 - 93
∠x = 87°
i think this is a open ended question but i agree with other guy who said you should ask it at english section
