You didn’t add a picture !
Lets try
centimeter is about 1/2 of a inch
if 28 square cm, the book coould be about 4m by 7cm (aoub the size of a recipt)
if 28 square in the book could be about 4in by 7in (regular size)
I would guess 28 square INCHES (cm is too smal)
Answer:
#10: 5/36
#11: 5/6
Step-by-step explanation:
#10:
The following combinations will get you 6.
1 - 5
2 - 4
3 - 3
4 - 2
5 - 1
These are only 5 of the 36 possible combinations, so you have 5/36 of a chance to get a combo of equal 6.
#11:
Like with #10, list the possible combinations that will get you 7.
1 - 6
2 - 5
3 - 4
4 - 3
5 - 2
6 - 1
That's only six combinations, but we're not including those. Subtract 6 from 36 to get 30. 30/36 simplifies to 5/6 (GCF of 30 & 36 is 6), so that is the answer to #11.

Please see the attached images for full solution.
For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.
Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.
Answer: EP is 12 and EO is about 10.91.
To find the length of EP, we can use the Pythagorean Theorem with the 2 legs of the right triangle it would form, EC and CP. CP would be 5 because it is the midpoint of the side.
5^2 + (EP)^2 = 13^2
EP = 12
Now, to find EO, we write and solve another Pythagorean Theorem equation using 12 for EP.
5^2 + (EO)^2 = 12^2
EO equals the square root of 119 or about 10.91.
