What is the value of x? sin(x+34)°=cos(2x+20)° Enter your answer in the box. x =
masha68 [24]

Answer:

The correct answer is -9.73°.

Step-by-step explanation:

The procedure is:

sin(x + 34)°=cos(2x+20)°

⇒ tan\frac{x+34}{2x+20} = 1 ; [assuming cos (2x+20)° \neq0]

⇒ x + 34 = 45 × ( 2x +20)

⇒ x + 34 = 90x + 900

⇒ 89x = -866

⇒ x = -9.73

and also 2x + 20 = 90° ⇒ x = 35°; but this does not satisfy the given equation.

Therefore the value of x is given by -9.73°.

lina2011 [118]

Answer:

16 is the range

Step-by-step explanation:

First, arrange the numbers from least to greatest.

21, 25, 25, 26, 28, 37

Then, subtract 21 (smallest number) from the 37 (biggest number).

37 - 21 = 16

So, the range is 16
