Question

What is the length of Line segment B C, rounded to the nearest tenth?

Answer 1

The length of line BC is 16. 12

How to determine the value

We have that;

• Line BD = 12
• Line AD = 5
• Line BC = unknown

Let's line BA, using Pythagorean theorem

BA =

$\sqrt{ {12}^{2} + {5}^{2} }$

BA =

$\sqrt{144 + 25}$

BA =

$\sqrt{169}$

BA = 13

Now, let's find BC

cos 30 = line BA/ line BC

0. 8660 = 14/ BC

cross multiply

BC = 14/0.8660

BC = 16. 12

Thus, the length of line BC is 16. 12
