If cot A = 1.96000 and the acute angle A has to be determined, which one of the following expressionswill give the seconds of the angle?

Answers

Answer 1

Answer: cot A = 1.96
tan A = 1 / cot A
tan A = 1 / 1.96
tan A = 0.510204082
A = tan^(-1) 0.510204082
A= 27.03086026°
A= 27° 0.03086026°
A= 27° 0.03086026° x (60' / 1°)
A= 27° 1.8516156'
A= 27° 1' 0.8516156'
A= 27° 1' 0.8516156' x (60" / 1')
A= 27° 1' 0.8516156 x 60"

Then the expression for the seconds is 0.8516156 x 60"

In Option A, we have (-0.00120)/(-0.00141) x 60" = 0.851063830 x 60"
In Option B, we have -0.00141/0.00120 x 60" = -1.175 x 60"
In Option C, we have 0.00806/0.01159 x 60" = 0.695427092 x 60"
In Option D, we have (-0.01159)/(-0.00806) x 60" = 1.437965261 x 60"

Answer: Option A: (-0.00120)/(-0.00141) x 60"

Answers

The expression equivalent to 16a + 24b is 8(2a + 3b).

What expression is equivalent?

In order to determine which expression is equivalent, the expression has to be simplified. To do this, divide the two terms, by factors of both terms.

The factors of a number are numbers that divide the original number evenly.

Factors of 16 and 24 = 1, 2, 4, 6, 8

The expressions could be:

2(8a + 12b)
