Ответ:
a. x = 5, AB = 14, BC = 8
Step-by-step explanation:
✔️Both triangles are similar, therefore their side lengths are proportional to each other.
Thus:
Cross multiply
Collect like terms
✔️AB = 2x + 4
Plug in the value of x
AB = 2(5) + 4
AB = 14
✔️BC = x + 3
Plug in the value of x
BC = 5 + 3
BC = 8
