45x/45= 1,072/45
x= 23 (rounded)
but, 45(23) is only 1035, which makes 7 pictures left over
to use those 7 you need 38 more picture to divide it evenly (because 45-7 = 38)
I guess 90 would be best option here, 37 celsius converts to 98 Fahrenheit but that’s to hot, 55 Celsius converts to 131 Fahrenheit is wayyyy to hot also and 70 Fahrenheit is to cold
Answer:
The parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Step-by-step explanation:
Given the parallelogram with sides 20 and 21 units with diagonal length 28 units.
we have to tell it is a rectangle or not.
The given parallelogram is rectangle if the angle at vertices are of 90° i.e the two triangle formed must be right angles i.e it must satisfy Pythagoras theorem
=
+![21^{2}](https://tex.z-dn.net/?f=21%5E%7B2%7D)
784=400+441=881
Not verified
∴ The sides of the parallelogram do not meet at right angles.
Hence, the parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
