Answer:
34 degrees.
Step-by-step explanation:
First of all, the sum of a triangle's degree is 180.
The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).
Now we now the two side, we can figure out the last side.
180-28-79= 73
The last angle is 73 degrees. However, we are looking for x.
x+39=73
All we have to do now is subtract 39 from 73, and that leaves us with 34.
Work backwards. If there were 14 at the end, then multiply this by 3/2 because 2/3 of the marbles were given to Sam. so 14 times 3/2 is 21. There were 28 total because if you add 1/3 to 1/6 you get 1/2. So they they lost 1/2 of the marbles and got 1/4 of the original amount back, which was 21.
So the original number was 28. Hope this helps!
Answer:
7
Step-by-step explanation:
Listing the factors of each number is one way, that is
factors of 35 : 1, 5, 7, 35
factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
The common factors are 1 and 7
The GCF is therefore 7
