Can someone tell me how to do that and the answer
ZanzabumX [31]

Answer:

43°

Step-by-step explanation:

The sum of all internal/interior angles of a triangle is always equal to 180°

Because of this, if the missing angle is x we can write the equation:

82°+55°+x=180° since the interior angles are given

Add like terms:

⇒ 137°+x=180°

Subtract 137:

⇒ x=43°
