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
Step-by-step explanation:
4x + 4 - 7x =
4x - 7x + 4 =
-3x + 4
