Answer:
24
Step-by-step explanation:
the wall meets the at a 45 degree angle and because of this we can draw a traingle allowing us to use the 45,45,90 method so then we do 12 times 2 and we get 24
Answer:
AB =
cm
Step-by-step explanation:
As we can see from the figure, BCDE is a square with each corner equal to 90°.
So that, BDE is a right triangle with corner BED equal to 90°
As BDE is a right triangle, according to Pythagoras theorem, we have:
cm
As the diagram s the cube, so that it can be seen that AD is perpendicular to the surface BCDE
=> AD is perpendicular to BD
=> ADB is the right triangle with corner ADB equal to 90°.
As ADB is the right triangle, ccording to Pythagoras theorem, we have:
cm
=>
cm
Conclusion: AB =
cm
Answer:
the answer is B.
Step-by-step explanation:
W= median is 58
R= median is 81
81-58=23
< = less than
> = greater than
57 is less than(<) x minus(-) 19
57 < x - 19
Your answer is the 4th option because:
The 1st option is not the answer because 19 is subtracted by x when it should be x minus 19, and the sign is > when it should be <
The 2nd option is not the answer because it should be x minus 19
The 3rd option is not the answer because the sign is > when it should be <
