Answer:

B) 8

Step-by-step explanation:

<h3>Given</h3>

x = 60°
BC = 4

AB = ?

<h3>Solution</h3>

Since x = 60°, the other acute angle A is 30°

We have 30-60-90 right triangle

<u>This triangle has side ratios: </u>

1 : √3 : 2

<u>The ratios give us:</u>

AB/BC = 2
AB = 2*BC
AB = 2*4
AB = 8

Correct choice is B
