Answer:

The answer is simply is 16.

Step-by-step explanation:

It is important to use PEMDAS. P stands for parenthesis, e stands for exponets, m stands for multiplication, d stands for division, a stands for addition, s stands for subtraction. So, lets start. Do we have any parenthesis? Yes, we do. That is (2+2). Well 2+2 is 4. Now your new equation would be 8/2(4). Do we have any exponets? No. do we have any multiplication? no. Do we have any division? yes.8/2 is 4. so now we have 4(4). And 4 times 4 is 16. Feel free to clarify if you have any questions.

Answer:

The length of rope is 20.0 ft . Hence, option (1) is correct.

Step-by-step explanation:

In the figure below AB represents pole having height 10 ft and AC represents the rope that is from the top of pole to the ground. BC represent the ground distance from base of tower to the rope.

The rope and the ground form a 30 degree angle that is the angle between BC and AC is 30°.

In right angled triangle ABC with right angle at B.

Since we have to find the length of rope that is the value of side AC.

Using trigonometric ratios

$\sin C=\frac{\text{perpendicular}}{\text{hypotenuse}}$
