3 0

Answer:

= 1

Step-by-step explanation:

tan(-x).cot(-x) 

tan(-x)  × cot(-x)

Note : cot =reciprocal or inverse of  tan = 1/ tan

Therefore

tan(-x)  × cot(-x)

= tan(-x)  × 1/tan(-x)

= tan(-x)  ÷ tan(-x)

= 1

Whats the normal arm span for these heights? : 4'10,4'11,5'0,5'4,5'5,5,'7,5'8,5'9,5'10,5'11,6'0
Svetllana [295]

 

In adults, the arm span is approximately 5 cm greater than the height in adult males and 1.2 cm in adult females. To calculate the arm span for the heights given, we add 5cm to their height. The following are the results:

 

Height                   Arm Span Length (in cm)

4’10                        152.32

4’11                        154.86

5’0                          157.4

5’4                          167.56

5’5                          170.10

5’7                          175.18

5’8                          177.72

5’9                          180.26

5’10                        182.80

5’11                        185.34

6’0                          187.88

 

To add, the total measurement of the length from the furthermost part of an individual's arms to the other end when raised equidistant to the ground at shoulder height at a 90º angle is called the arm span or wingspan.
