ANGLE B = 65 DEGREE , ANGLE C = 45 DEGREE , IN TRIANGLE ABC AND DE PARALLEL TO BC. IF ANGLE DOB = X DEGREE , ANGLE EAC = Y DEGREE. FIND THE VALUE OF X AND Y

Answer 1

angle b 65 and angle c 45
65+ 45
110
if triangle abc = 180
de is parallel to bc then
angle dob = 65
angle eac = 45
65- 45 = 20
value of x and y = 20
