I am a 2 dimensional shape that had 5 obtuse angles
Montano1993 [528]

Answer:

A pentagon.

Step-by-step explanation:

A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.

108° ≥ 90°,  so the angles are obtuse.

Therefore, a 2-D shape with 5 obtuse angles is a <u>pentagon</u>.

2x - 4y = -8<br> Solve for y <br><br><br> Need help ASAP!
goldenfox [79]

Answer:

y = 1/2x + 2

Step-by-step explanation:

  • 2x - 4y = -8

<u>Solving for y in steps:</u>

  • 2x - 4y + 8 + 4y= 4y
  • 2x + 8 = 4y
  • x + 4 = 2y
  • y = x/2 + 4/2
  • y = 1/2x + 2

Surface area is the sum of the areas of each side of a three dimensional object.

There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.

So the surface area is:

2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2

Find the sine, cosine, and tangent of 45 degrees.
frosja888 [35]

Answer:

The correct answer is option C.

Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1

Step-by-step explanation:

The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.

The table is easily available on the internet.

WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.

The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.

So

Sin 45 = √2/2

Cos 45 = √2/2

and

Tan 45 = 1

So the correct option is C.
