Question

In the given figure angle b is equal to 65 degree and Angle C is equal to 45 degrees in triangle a b c and d a e parallel to BC if angle d a b is equals to X degree and angle BAC is equal to Y degree find the value of x and y

Answer 1

Answer:

x= 65 because of alternate interior angle

sum of angle 180°

180-105=75

Answer 2

X = 65 & Y = 70  if angle d a b is equals to X degree and angle BAC is equal to Y degree

Step-by-step explanation:

∠B = 65°

∠C - 45°

in ΔABC

∠A + ∠B + ∠C = 180°

=> ∠A + 65° + 45° = 180°

=> ∠A  = 70°

∠BAC = ∠A  = 70°

=> Y = 70

DAE ║ BC

=> ∠DAB = ∠ABC  

=> ∠DAB = ∠B

=> ∠DAB = 65°

=> X = 65
