Answer:
John should use a protractor to measure an angle of 70°.
Step-by-step explanation:
70° is an angle for which there is no construction procedure.
Angles of measures 15°, 18°, 30°, 36°, and 45° can be constructed, along with their supplements, complements, and values multiplied by any positive integer or divided by any power of 2. Of course, the sums and differences of any of these angles can be constructed. (The more steps in the construction, the greater the loss of accuracy.)
Because there is no construction procedure for an angle of 70°, John must create the angle using a measuring tool. A protractor is the tool of choice.
John should use a protractor to measure an angle of 70° relative to one end of his 5 cm baseline.

<em>Comment on John's technique</em>
It is likely John would create a more accurate representation of the desired triangle by drawing the 7 cm segment first. This would give a longer baseline for use with the protractor, and would mean the length through the point marked using the protractor would not have to be extrapolated as far.
Answer:
48.5 cm
Step-by-step explanation:
For this you can use the Pythagorean theorem. You know that your hypotenuse will be 56 cm, and one side will be half of that, 28. This sets up the equation:
a^2+28^2=56^2
So, a^2 is 2,352
And a, rounded to the nearest hundredth, is 48.5 cm
Hope this helps :)
First let's find out what would the sides of a square be.
7500 / 4 = 1875
Now we have 1875 as the sides and double at the top.
So 1875 * 3750 = 7031250 meters squared
X<8
because your number is x, and use < to represent the less sign. Remember, that always have the sign facing out ward when it says x is less than (number)
Answer:
smaller number = 623
middle number = 625
larger number = 627
Step-by-step explanation:
Variable: X = smallest number
If these numbers are consecutive and odd, then the numbers would be:
x, x+2, x+4
x + (x + 2) + (x + 4)= 1875
3x + 6 = 1875
3x = 1869
x = 623
x + 2 = 625
x + 4 = 627
Check:
623 + 625 + 627 = 1875
