I believe the answer is -27
Answer:
-5
Step-by-step explanation:
<u>Given that , </u>
- A number is taken away from 40 and the result is 45 .
<u>L</u><u>et </u><u>:</u><u>-</u><u> </u>
- The required number be x .
<u>According</u><u> to</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>
40 - x = 45
- x = 45 - 40
- x = 5
x = -5
<h3>
Hence the required answer is -5 .</h3>
so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.
Answer:
25 inches
Step-by-step explanation:
If square has a perimeter of 20 inches, the length of each side is:

After cutting the square in half, we are left with two rectangles of 5 in x 2.5 in
Attaching those two smaller rectangles by their short end (2.5 in side), gives us a new rectangle with a height of 2.5 in and a length of 10 in (sum of the 5 in sides in each rectangle). The perimeter of this new rectangle is:

The perimeter is 25 inches.
