Solution:
Given:

Lets First Differentiate the given equation with respect to x



-----------------------(1)
this can be rewritten as

Now differentiating again with respect to x

Now substituting (1) we get



At(1,2) 



You need to measure the parallel lines on and add them
Answer:
22⁰
Step-by-step explanation:
By angle sum property :
x + 127 + 31 = 180⁰
x = 180 - 158
x = 22⁰
There are 120 blocks left.
Answer:
x=1
Step-by-step explanation:
In order to solve this equation, we must add 7 to each side. This gives us x=1
