Answer:
<h2> P = 98 cm</h2>
Step-by-step explanation:
Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

Perimeter:
P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
Answer:

Step-by-step explanation:
Given


Required
The distance between the top and John
The distance is calculated using:

Where
--- the angle between the diagonal line and the vertical line


So, we have:






<em> --- approximated</em>
Answer:
5. I agree with your answer choice.
6. 13.3
Step-by-step explanation:
5. You have m∠1 = 90° = m∠2, so it is reasonable to invoke the transitive property. (Step 4 would use "angles with the same measure are congruent" to complete the proof.)
6. The difference in x-coordinates is (4-1) = 3. The difference in y-coordinates is (22-9) = 13. By the Pythagorean theorem, the distance between the points is ...
... √(3² +13²) = √178 ≈ 13.342 ≈ 13.3
answer: Rolling Two Dice. Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.
Step-by-step explanation: hopefully this is right
