Answer:
Step-by-step explanation:
CA and CB are both opposite equal 90 degree angles so are equal so we can say
8x-12=4x
4x-12=0
4x=12
x=3, since CA=4x
CA=4(3)=12
6 repeating so the answer would be 31.666666..... or round it up 31.666666667

Answer:
2
Step-by-step explanation:
7 ( 2 e - 1 ) - 3 = 6 + 6 e
Expand brackets
14 e - 7 - 3 = 6 + 6 e
Simplify
14 e - 10 = 6 + 6 e
Minus 6 e from both sides
8 e - 10 = 6
Add 10 on both sides
8 e = 16
Divide by 8 from both sides
e = 2
