3. Triangle ABC is isosceles with AB = AC. The angles are as shown in the diagram.
A
x +41
2x - 18
B
5y-8
С
(a) Write down two simultaneous equations, in terms of x and y, to represent this
information.
(b) Solve the simultaneous equations to find the sizes of the angles of the triangle.
(A is the top of the triangle whereas B and C are equal at the bottom)
