Answer:

  • B) 8

Step-by-step explanation:

<h3>Given</h3>
  • x = 60°
  • BC = 4
<h3>To find</h3>
  • 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
