Answer:

x = 31

Step-by-step explanation:

The 88-deg angle is an exterior angle of the triangle.

The 57-deg angle and x are its remote interior angles.

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

x + 57 = 88

x = 31

Answer:

x = 31º

Step-by-step explanation:

The inside of a triangle equals 180º. We are given one of the angles and we need to solve for those. First things first, we should solve the one on the left of the x. We know that a straight line equals 180º and we already have one angle. So, our equation should look like

180 - 88 = x, 180 - 88 = 92

So there's our second angle. Now, we can add then together and subtract by 180.

57 + 92 = 149

180 - 149 = 31

Answer:

It is angle k and angle l

Step-by-step explanation:

When opposite sides are given, especially for a right triangle, the longer the length the bigger the angle. The hypotenuse, which is across the right angle is always longest. The shortest side will always have the smallest angle. Check the image if it helps.
