The value of cos 45 in a right angle triangle is 1/√2.

<h3 /><h3>What is the trigonometry ratio?</h3>

The trigonometry ratios are ratios that can be used to determine the side and angles of a triangle depending on the known parameter. The basic trigonometry ratios are denoted by the acronym: SOH CAH TOA

i.e.

  • Sin θ = opp/hyp
  • Cos θ = adj/hyp
  • Tan θ = opp/adj

From the given diagram, we are to find the Cos 45°

i.e.

θ = 45°

Let's recall the angle 45 45 90 theorem that states that right angles have the following values for the sides:

  • hypotenuse = √2
  • opposite = 1
  • adjacent = 1

Since

Cos θ = adj/hyp

Cos 45 = 1/√2

Answer:

C: (-8,3) R:5

Step-by-step explanation:

The equation of a circle can be written as:

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center, and r is the radius

We have the equation:

(x+8)^2+(y-3)^2=25

Center:

The center is (-8,3)

(x+8)^2--> (x-h)^2

Therefore the x coordinate of the center is -8

(y-3)^2-->(y-k)^2

Therefore the y coordinate of the center is 3

Radius

r^2=25

Take the square root of both sides

\sqrt{r^2}=\sqrt{25}

r=5

Jackson is 5 years old. His brother Micah is 20 years older than him. Which equation represents Micah's age in comparison with J
mina [271]

Answer:

M=5+20

Step-by-step explanation:

I’m using M for representing Micah’s age.

This would represent Micah’s age because it says that Micah is 20 years older than Jackson, who is 5. Therefore, you would just need to add 5 and 20 together. Micah is 25 years old.

Reily adds 45.3 and 3.21.should his sum be greater than or less than 48?Tell how you know.
Eddi Din [679]


Greater than 48, because just taking whole numbers 45 + 3  = 48 already.

45.3 is greater than 45 and 3.21 is greater than 3

Graph and Label the Points on the coordinate plane below
Lapatulllka [165]
In order to graph these, you need to understand the X and Y axis.

The X-Axis contains the first number in your ordered pair, and goes left, right (horizontally) for example the first ordered pair you have.

(2,5 1/2). To do this, move 2 spaces to the right on your X-axis. now go 5 and a half spaces up, and plot the point.


(-2 1/2, 0.5) For this one, you move 2 and a half spaces to the left on the X-axis, and half a space up. put a point there.


(3.5, -4 1/2) move 3 and a half spaces to the right on your X-axis, and go 4 and a half spaces down. put a point there.

let me know if you have questions! :)
