Best ResponseYou've already chosen the best response.1I have filledin the angles that can be worked out directly and labelled the rest as follows: dw:1325721373971:dw m<BCA = m<CBE + m<CEB (external angle of a triangle) 75 = alpha + beta < (1) m<BCA + m<BCD + m<DCE = 180 (angle on a straight line) 75 + 180  2alpha + beta = 180 75 = 2alpha  beta < (2) 2*(1)  (2) gives: 75 = 3beta 25 = beta
