Answer:

5 meters

Step-by-step explanation:

If in 1 inch have 2.54 centimeters, in 197 inches will have:

197×2.54 = 500.38 centimeters

If 100 centimeters are 1 meter, 500 centimeters will have 5 meters, so 197 inches have 5 meters

How is constructing an angle bisector similar to constructing a perpendicular bisector?
A. Both constructions begin with a given angle
B. Both constructions allow you to find the midpoint of a segment.
C. Both constructions require that you draw a ray.
D. Both constructions require the point where two arcs intersect.

Answers

Answer:

D. Both constructions require the point where two arcs intersect.

Step-by-step explanation:

D is your answer

Both constructions require the point where two arcs intersect. Then the correct option is D.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Building an angle bisector is similar to building a perpendicular bisector in that both constructs call for the intersection of two arcs.

Angle bisector means dividing an angle into two equal parts. And the perpendicular bisector means the line is divided into two equal line segments.

Both constructions require the point where two arcs intersect.

Then the correct option is D.

Answer: x = 3

Step-by-step explanation:

Given

x/3 + 3 = 4

Subtract 3 on both sides

x/3 + 3 - 3 = 4 - 3

x/3 = 1

Multiply 3 on both sides

Answer:

(1,-1)

Step-by-step explanation:

when x is changed by 6 units to the right, you add 6

-5 + 6 = 1

when y is changed by 2 units down, you subtract 2

1 - 2 = -1

Explanation:

To find a coterminal angle, we add on 360 degrees

-59+360 = 301

The angles -59 degrees and 301 degrees point in the same exact direction. This is why they are coterminal.

solve this i am not able to solve​

Answers

Answer:

Step-by-step explanation:

First we need to set this ratio up in the coordinate plane. Because this is tangent, the 3 goes opposite the reference angle and the 4 goes along the x-axis, adjacent to the reference angle. We see that we are missing the third side of the triangle when we do this, namely the hypotenuse. We use Pythagorean's Theorem to find that this side is 5. Now we have to deal with the identities for each sin(2A) and cos(2A).

sin(2A) = 2sin(A)cos(A)

We know from the triangle we drew in the coordinate plane that

[tex]sin(A)=\frac{3}{5}[/tex]  and  [tex]cos(A)=\frac{4}{5}[/tex] so we fill in the formula accordingly and then simplify:

[tex]sin(2A)=2(\frac{3}{5})(\frac{4}{5})=\frac{24}{25}[/tex]

cos(2A) has 3 identities; I just picked the one I thought would be easiest to use and went with that one. Regardless of which one you pick you will get the same answer as long as you do the math correctly.

[tex]cos(2A)=cos^2(A)-sin^2(A)[/tex] and filling in the formula:

[tex]cos(2A)=(\frac{4}{5})^2-(\frac{3}{5})^2\\cos(2A)=\frac{16}{25}-\frac{9}{25}\\cos(2A)=\frac{7}{25}[/tex]

I'm not sure why you have 7/2 there...
