Answer:
x = 19.
Step-by-step explanation:
By the tangent - secant theorem:
BD^2 = AB * EB
so:
8^2 = (x - 7 + 4) * 4
4(x - 3) = 64
4x - 12 = 64
4x = 64 + 12 = 76
x = 76/4
= 19.
6y- 12x =24
6y= 24+12x
y=4+2x
I’m not entirely sure, but I think that if the y-value is not included, it should equal 0.
1st number: 4
2nd number: 3
4+3=7
4*4=16 ; 5*3= 15
16-15=1
