You can do this because when you cut the rectangle in half with the diagonal, it forms a right triangle, making the diagonal the hypotenuse (c).
Diagonal: 62.48 inches

Answer:
The angle that the ladder made with the ground = 53.13010235°
Step-by-step explanation:
The ladder has a length of 10 ft and it leaned against a wall to form a right angle triangle. The height from the top of the ladder to the ground is given as 8 ft. The triangle formed from the illustration can be represented with the picture below.
The angle A is the angle the ladder made with the ground.
Length of ladder = c
height from the top of the ladder to the ground = a
The distance of the foot of the ladder and the wall = b
c = 10 ft
a = 8 ft
Using SOHCAHTOA
sin A = a/c
sin A = 8/10
sin A = 0.8
A = sin-1 0.8
A = 53.13010235°
sin = opposite/hypotenuse
¢=angle
sin¢=8/10
sin¢= 0.8
arcsin¢=arcsin(0.8)
¢= 53.13 degrees

Answer:
- The 0.2 in the expression could be changed to 2
Step-by-step explanation:
Each column of the table represents:
- 20% = 0.2 = 14
To determine 40% the expression should be:
- 2*20% = 2*14
So the correct answer choice is the last one:
- The 0.2 in the expression could be changed to 2
The change in the expression to get the correct answer is option B. Mikel should changes the 0.2 in her expression to 0.4.The correct expression for 40% of 70 is (0.4)(70) = 28.
Mikel's expression is (0.2)(14) = 2.8.
The only change that needs to be made to Mikel's expression is to change the 0.2 to 0.4.
This is because 40% is equivalent to 0.4.
So the answer is to change the 0.2 in Mikel's expression to 0.4.
Here is a breakdown of the calculation:
40% of 70
= 40/100 × 70
= 28
(0.2)(14)
= 0.2 × 14
= 2.8
As it can be seen, the only difference between the two expressions is the value of the first factor.
In the correct expression, the first factor is 0.4, while in Mikel's expression, the first factor is 0.2.
Therefore, if Mikel changes the 0.2 in her expression to 0.4, then her expression will be correct.
