Which equation can you use to solve for x

Answers

As for a specific equation, I could not say. However, I can tell you how to find x!

The first thing to remember is that a straight line has a 180 degree angle.

You see on the bottom side that we have a 146 degree angle. Now look at the top side. Look closely, and you will see that the two sides are actually identical!

Don't see it? Look at the line on top between x and 56, and imagine it is not there. You see that we actually have the same 146 degree angle, just flipped right side up!

However, this angle does not say 146, but makes an extra line between them with x and 56. This means that x + 56 equals 146!

So we can find x by subtracting 56, from 146, which is... 90!

I am a polygon with four congruent sides. draw me and name me

Answers

A polygon with four congruent sides is a square, or a diamond. This may apply if it also has four right angles.
Another option may be a rhombus, which will apply if it does NOT have any right angles.

Remember: Congruent means the same.

Your answer is a square.

Answer:

Rhombus: A quadrilateral with four congruent sides; a rhombus is both a kite and a parallelogram. Rectangle: A quadrilateral with four right angles; a rectangle is a type of parallelogram. Square: A quadrilateral with four congruent sides and four right angles; a square is both a rhombus and a rectangle.

I’m confused can someone help and answer?

Answers

The radius is 5 inches, so r = 5
The height is 30 inches, so h = 30
We'll use pi = 3.14

Plug in the given values and then use PEMDAS to simplify
SA = Surface Area
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*5^2 + 2*3.14*5*30
SA = 2*3.14*25 + 2*3.14*5*30
SA = 6.28*25 + 6.28*150
SA = 157 + 942
SA = 1099

Answer: 1099

Just plug in the radius (5 in) for the 2 r's in your equation and the height (30 in) for the h in your equation.

SA=(2×3.14×5^2)+(2×3.14×5×30)
SS=(2×3.14×25)+(2×3.14×5×30)
SA=157+942
SA=1099 sq inches
