M∠LMJ = 162°; m∠JMI = 18°If ∠KMJ and ∠JMI are complementary angles, then what is the measure of ∠KMJ

Answers

Answer:

m∠KMJ = 72°

Step-by-step explanation:

How many sides and right angle and parallel sides a triangle had

Answers

-- Every triangle has three (3) sides and three angles.
If it doesn't, then it's not a triangle.

-- A triangle can have one right angle, and no more than one. But it
doesn't need to have one, and triangles don't always have one.

-- A triangle never has any parallel sides.
