Answer:
x =1+i√11/2,1−i√11/2
Step-by-step explanation:
/2 means that everything before it is divided by 2. Basically, each side is divided by 2, it just wont let me do that function on here ;)
Hope this helps!
Step-by-step explanation:
first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).
the area is : 1/2 × perimeter × apothem
the perimeter is simply 12 × 5 = 60 meters.
apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =
= 9.330127019... meters
so the area is
1/2 × 60 × 9.330127019... = 279.9038106... m²
therefore, the third answer option is correct (although it is m², and not m³).
by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.
The letters of each proposed conguency statement need to be in corresponding positions of the original congruency statement
For example, consider the first answer selection. The letters on the left (CBA) are the 3rd, 2nd, and 1st letters of the original congruency statement. The letters on the right (MNL) are the 2nd, 3rd, and 1st letters of the original. The order 321 is not the same as the order 231, so the first choice is <em>incorrect</em>.
Appropriate choices are
∆BAC ≅ ∆MLN . . . . 3rd choice
∆ACB ≅ ∆LNM . . . . 4th choice
Answer:
6 * squ 2
Step-by-step explanation:
squ 6 * squ 12 = squ 6*12 = squ 72 = squ 36 * 2 = 6 * squ 2
