Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92
Use the quadratic formula .
x^2-2x+11=0
a=1
b=-2
c=11
x=-2+- (-2)^2-4*1*11 divided by 2
x=2+- the square root of -40 divided by 2
There is no real solutions
9/20 plus 3/20 equals to 12/20, which is equal to 6/10, which is equal to 3/5
Change in a with respect to x
pounds per foot would be the unit
lb/ft
