Answer:
cos Θ = 
Step-by-step explanation:
Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by
h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
h = 
In relation to Θ, 4 is adjacent and 5 is opposite, thus
cos Θ = 
=
Answer:
Option A
Step-by-step explanation:
2x^2+10x+12
Divide through by 2
x^2 +5x+6=0
x^2 +3x+2x+6
x(x+3)+2(x+3)=0
(x+2)(x+3)=o
x=-2 or x=-3
Answer:
2

Answer: 2
15x^2 + 12x +10x + 8= 0 reduced 15x^2 +22x+ 8 = 0
Answer:
-2y=10-5x
Step-by-step explanation:
5x-2y=10
you want to get the y by itself
so you would subtract the 5x from both sides
-2y=10-5x
