Answer:
What is the question???
Step-by-step explanation:
Answer:15
Step-by-step explanation:
27+x=42 alternate angles are equal
Collect like terms
x=42-27
x=15
Given :
a-b = c-d ...1)
b = d-1 ...2)
c = 6
To Prove :
a = 5
Solution :
Adding equation 1 and 2, we get :
(a-b) + (b) = (c-d) + (d-1)
a = c -1 ...3)
Putting given value of c = 6 in above equation, we get :
a = 6 - 1
a = 5
Hence, proved.
