The best choice would probably be the third option from the top. Since by using the distance formula you can solve for the length or distance of each of the sides of the triangle, and check to see if it is equal. As would be in an equilateral triangle.
Slope wouldn’t be best for the last leg or bottom leg as there is no change in y and x.
Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0
multiply thru the top equation by 2
Multiply thru the bottom equation by 3
4a + 6b = 12
15a+ 6b = 12
Subtract and solve for "a":
11a = 0
a = 0
Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
Answer:
C. 52 is the correct answer
Step-by-step explanation:
Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is
Simplify it:
Answer: y=4
Step-by-step explanation:
We have a khown angle wich is 30 degree .
Cos 30 = root square of 3 /2
So root sqaure of 3/2 = 4 root square 3 / x
X= 4 r.sq 3 / r.sq 3/2 = 8
So we just need to apply the pythagorian theorem
X^2= y^2+ 48
64 = y^2 +48
Y^2 = 16
Y=4
