Question

Please give me answer of all questions step by step .​

Answer 1

Answer:

a) x = 33 Degrees

b) x = 100 Degrees

c) x = 50 Degrees

d) x = 65 Degrees, y = 135 Degrees

Step-by-step explanation:

a => 72 + x = 105 (sum of two interior angles = one exterior angle)

x = 105 - 72 = 33

b => Same concept => 65 + 35 = x (exterior angle)

c => Same concept 60 + x = 110

x = 110 - 60 = 50

d => x = 180 - (70+45) = 180 - 115 = 65

=>    y = 70 + 65 or (180 - 45 -> Linear Pair) = 135 Degrees
