Answer:

a = 117 , b = 117 , c = 63 , d = 78

Explanation:

Assuming you require the values of a , b , c , d

a and 117 are vertically opposite angles and are congruent (equal) , so

a = 117

-------------------

b and a are alternate angles and are congruent , then

b = a = 117

------------------

b and c are a linear pair and sum to 180, that is

b + c = 180 ( substitute b = 117 )

117 + c = 180 ( subtract 117 from both sides )

c = 63

--------------------

d and 78 are corresponding angles and are congruent , so

d = 78
