Find the slope of the line slope=b=

34

Step-by-step explanation:

*A triangle has an interior angle of 180 degrees

We know that one of the angle is 112 degree

180 - 112 = 68 degrees

We also know that the triangle is an isosceles triangle which means both sides and both angles are the same ( we can determine that it's an isosceles because of the two lines)

68 / 2 = 34

R = 34 degrees

T = 34 degrees

S = 112 degrees
