Hello,
i would go for A)
take it as a guess
Answer:Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
Hope this helped
Answer:
22.25
Step-by-step explanation:
1302-1124/2016-2008
Answer:
cosR = 
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR =
=
= 
Answer:
x=17
Step-by-step explanation:
These are corresponding angles, meaning they have the same measure. We must set them equal to each other.
