15. The figure below, not draw to scale, is made up of an isosceles triangle and a rhombus. /_a = /_d, /_c is twice /_b, /_a is twice /_e and /_b is greater than /_e by 48o.
a) Find the value of /_ e.
b) Find the value of /_ b.
a = d
c = 2 b
a = 2 e
b = e + 48
a + 2 b = 180
2 e + 2 (e + 48) = 180
4 e = 180 – 96
e = 84 ÷ 4 = 21
b = 21 + 48 = 69
a) /_e = 21o
b) /_b = 69 o
