Question

SOMEONE HELP ME PLEASE

Answer 1

Answer:

$\frac{11}{2}$

Step-by-step explanation:

$\frac{x}{AB}$=cos60

x=$\frac{AB}{2}$=$\frac{11}{2}$

in a right angled triangle cosA=$\frac{adjacent}{hypotenuse}$

so cosB=$\frac{x}{11}$

$\frac{1}{2}$=$\frac{x}{11}$

x=$\frac{11}{2}$

Answer 2

Answer:

• 5.5 units

Step-by-step explanation:

x is the smallest side because it is opposite of 30° angle.

The side opposite to 30° is half the hypotenuse:

• BC = AB/2
• x = 11/2
• x = 5.5
