Question

BC = 6x + 5 . AC = 98 and AB = 8x + 9 Find BC.

Answer 1

BC = 41 degrees

Explanation:

You know that AB + BC = AC, so:

8x + 9 + 6x + 5 = 98

14x + 14 = 98

14x = 84

x = 6

BC = 6x + 5

substitute in x = 6:

BC = 6 * 6 + 5

= 36 + 5

= 41

Answer 2

Answer: BC = 41

Explanation:

AB + BC = AC

8x + 9 + 6x + 5 = 98

14x + 14 = 98

14x = 84

x = 6

BC = 6x + 5

Substitute 6 for x

BC = 6 (6) + 5

BC = 36 + 5 = 41

Hope it helps!
