Answer:
a) A triangle which the angles ratio is 1 : 2 : 3 is a 30º - 60º - 90º right triangle.
b) The shortest side is opposite to the shortest angle. So, we can calculate it using sin 30º.
Answer:
C
The problem:
What can x not be so that the following is a function:
(8,5), (6, 8), (X, 11), (0, 12)?
Step-by-step explanation:
A set of points is a function if every element,x, in the domain is paired with one y from the range.
So basically we don't want any repeated x. x would be a repeat if x is 8 since it has already been paired with 5.
Summary we are saying x can't be 8 because x=8 is already paired with y=5 so we can't pair it with another different y.
4x+y= x
Move all x term to left side
4x-x+y=0
Subtract 4x from 3x
3x+y=0
Move y term to right side
3x= -y
Divide both sides by 3
X= -y/3
Ok so if it's
4x+y= z solve for x
Move y to right side
4x= -y +z
Now divide both by 4 to get x alone
X= -y/4 + z/4
Answer:
11/15
Step-by-step explanation:
22 = 11 x 2
30 = 15 x 2
Divide each number in the original fraction by 2
