Answer:
3^2 + x^2 = 9^2
9 + x^2 = 81
x^2 = 72
x =
, which is about 8.5
Cosine X = 3/9
Cosine X = 1/3
angle x= 70.5
If angle x= 70.5, angle z = 19.5 degrees.
Let me know if this helps!
Answer:
B
Step-by-step explanation:
V=8, did it on equations solver
Answer:
C is correct
Step-by-step explanation:
Given: System of linear inequality


First we will draw the graph of system of equation and then see the correct option.
Equation 1: 
We will make the table.
x : -2 0 2
y : 1 0 -1
Test Point: (0,4)
0<-2 ( False )
Shaded area away from (0,4)
Equation 2:
We will make the table.
x : -2 0 2
y : -1 3 7
Test Point: (0,4)
4≥3 ( True )
Shaded area towards (0,4)
Please see attachment for graph.
Hence, C is common shaded area (region)
let's first off apply a log rule of cancellation, keeping in mind that, first off is ln(), not in(), and that ln() is just a shortcut to logₑ.
