32)
b) The third angle is 54°.
c) Isosceles triangle
EXPLANATION
ΔTWL has two angles 63 degrees.
The sketch is as follows;
b) To find the measure of the third angle, let x represents the third angle.
63+ 63 + x = 180° (sum of interior angle of a triangle)
126 + x = 180°
Subtract 126 from both-side of the equation.
x = 180° - 126°
x = 54°
Hence, the third angle is 54°.
c) ΔTWL has two equal angle and two equal sides, this makes the triangle an Isosceles triangle.
