Find cosθ, cscθ, and tanθ, where θ is the angle shown in the figure. Give exact values, not decimal approximations.
NNADVOKAT [17]

Answer:

see explanation

Step-by-step explanation:

To find cscθ we require to find the third side of the triangle.

let 3rd side be x and using Pythagoras' identity

x² + 8² = 9²

x² + 64 = 81 ( subtract 64 from both sides )

x² = 17 ( take square root of both sides )

x = \sqrt{17}

Then

cosθ = \frac{adjacent }{hypotenuse} = \frac{8}{9}

cscθ = \frac{hypotenuse}{opposite} = \frac{9}{\sqrt{17} }

tanθ = \frac{opposite}{adjacent} = \frac{\sqrt{17} }{8}

Which point is located at (5, –2)?
siniylev [52]
Answer:
The correct answer is point D (5, negative 2)

Explanation:
The original point asked in the problem says (5, -2). When a number is positive, you do not have to annunciate that it is; in this problem you’d just say the number 5. This being said you can eliminate point A and point C. When listing a number on a coordinate plane you say it as it is. In this case, you would say “five, negative two” rewritten as (5,-2). This would eliminate point B because it is out of order and would bring you into a totally different quadrant. Point D is the only left answer making it correct. Hope this helps !!

aleksklad [387]

Answer:

63.2 = y

Step-by-step explanation:

The perimeter is the sum of all the sides

P = 7.8+ y+37.6 + y

171.8 = 7.8+ y+37.6 + y

Combine like terms

171.8 = 45.4 + 2y

Subtract 45.4 from both sides

171.8-45.4 = 45.4 + 2y -45.4

126.4 = 2y

Divide each side by 2

126.4/2 = 2y/2

63.2 = y
