Find the area of a square with diagonals of length 9root2​

Mathematics
1 answer:
igomit [66]3 years ago
5 0

Answer:

A=162

Step-by-step explanation:

The are of a square is A=a^{2} so 9 root 2 is 9\sqrt{2}  since the formula says that a need to be squared so we need to square 9 root 2 (9\sqrt{2})^{2} which would be 162 or another way would be to turn 9 root 2 into a decimal 9\sqrt{2}   = 12.727292206...then you would square that number just like we did in the first example  (12.7272206)^{2} which would give you 161.98 then all you have to do is round to the nearest tent then you would get 162 as an answer

i would agree that this step requires to much work so just stick with the first way to do it.

thank you for waiting for this answers i hope it helps a lot i went into details to make sure that you understand if you still don't get it just post another question ill be more than happy to help you out.

How do I find these angle measures?
ch4aika [34]
The measure of angle 1 is 75 degrees because it is a corresponding angle with the one given of 75 degrees
the measure of angle 2 is 105 degrees because it forms a supplementary angle with the one next to it that is 75 degrees. (this means they add up to 180 degrees.

For a project, Gabrielle made a model of an Egyptian pyramid. The square base has a side length measuring 10 inches. The pyramid
Varvara68 [4.7K]
The pyramid is shown in the diagram below.
The pyramid is built from four congruent triangles and one square as the base

We have the side of the square, so the area is = 10×10 = 100

We need the height of the triangle to work out its area. We can find out by using the height of the pyramid and half of the length of the side of the square.

Using the Pythagoras rule
Height of triangle = \sqrt{12^{2}+ 5^{2} } =13

Area of one triangle = 1/2×10×12=60
Surface area of the pyramid = 100 + (4×60) = 340 square inches

Beth left school driving toward the lake one hour before tim. tim drove in the opposite direction going 6 mph slower than beth f
m_a_m_a [10]

Beth's speed was 60 mph.

<h3>What is speed?</h3>
  • The speed (commonly referred to as v) of an object in everyday use and kinematics is the magnitude of the change in its position over time or the magnitude of the change in its position per unit of time; it is thus a scalar quantity.
  • The distance traveled by an object in a time interval is divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
  • Velocity is not the same as speed.

To find what was Beth's speed:

Beth's data:

  • time = 2 hrs; rate = r mph; distance = r×t = 2r miles

Tim's data:

  • time = 1 hr; rate = r-6 mph; distance = r-6 miles

Equation:

  • distance + distance = 174 miles

So,

  • 2r + r - 6 = 174
  • 3r - 6 = 174
  • 3r = 180
  • r = 60 mph (Beth's rate)
  • r-6 = 54 mph (Tims's rate)

Therefore, Beth's speed was 60 mph.
