Answer:
42 degrees
Step-by-step explanation:
angle is x
supplement is 180-x
x+96=180-x, since it is 96 less than its supplement
2x=84
x=42
180-x=138
The angle is 42 degrees.
Answer:

Step-by-step explanation:
Given


Required
The length of the diagonals
First, calculate the length of AB using:

So, we have:




The diagonal of a square is calculated using:

Where x is the length of each side.
So:


-- approximated
V+8*v-3
v+v=2v
8+-3=5
Equation would be: 2v*5 because you cannot combine unlike terms
your answer: 7 (b+x) + 7 (b+y)
If You do the distributive property you will get:
7bx+7by
P(4) = 4(4) - 1
therefore, p(4)= 15
