Answer:
Step-by-step explanation:
65+3x-1=4+8x(the sum of two interior opposite angle are equal to the exterior angle formed)
64+3x=4+8x
64-4=8x-3x
60=5x
60/5=x
12=x
substitute the value of x
4+8x
4+8*12
4+96
100
therefore angle ZAB=100 degree

Answer:
c or the third one
Step-by-step explanation:
Answer:
Let Jody's Age be X
Then Jody's Brother age is: 2x - 3
Total is: (2x - 3) + x = 30
Now we solve for x
2x - 3+ x = 30
3x - 3 = 30
3x = 30 + 3
3x = 33
x = 33/3
x = 11
Therefore the age of Jody's Brother is (2×11) - 3 = 19
