A prime number is a number that can only be divided for 1 and itself.
The right answer is B, 1053 is NOT prime. It can be divided for 1, 3, 9, 13, 27, 39, 81, 117, 351, 1053.
Answer:
AC=18
Step-by-step explanation:
To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²
144-64=b²
80=b²
√80=√b²
8.94427191=b
That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.
AC= 18
C and E are the right ones
