Answer:
y= 11.4
Step-by-step explanation:
In an equilateral triangle, each angle is the same
180/3=60
So each angle equals 60
5y+3 =60
Subtract 3 from each side
5y +3-3 = 60-3
5y = 57
Divide by 5
5y/5 = 57/5
y = 11.4
The trick to solving this problem is to know and remember that the sum of all the interior angles of a triangle is always 180 degrees.
Thus, (6x+1) + (5x-17) + (9x-24) = 180.
20x = -40, so x = -2 (answer)
Answer:
CDJ= 34
Step-by-step explanation:
We know that ADJ = 90 degrees
ADK = 180 degrees and JDK equals 90 degrees so ADJ must equal 90 degrees
ADJ = ADC+CDJ
ADJ =4x+ 3x-8
Since ADJ = 90 degrees
90 = 4x+3x-8
Combine like terms
90 = 7x-8
Add 8 to each side
90+8 = 7x-8+8
98 = 7x
Divide each side by 7
98/7 = 7x/7
14 =x
We want to know CDJ
CDJ = 3x-8
CDJ = 3(14) -8
CDJ = 42-8
CDJ= 34
Y=-3x-11. you add the one to the other side making the equation y=-3(x+4)+1
then you distribute making it y=-3x-12+1
Answer:
y + 4 = 2(x+1)
Step-by-step explanation:
Begin by calculating the slope m using the slope formula. Then substitute m and (-1,-4) into the point slope form. The point slope form of the line is 
.
Slope Formula:
Substitute m = 2 and (-1,-4).
