Answer:
Step-by-step explanation:
Since it is an equilaterla triangle, we can see the side opposite to that of side length 4 is 60 degrees. Since the other angle is a right angle (90 degrees), we can find that the other side is 30 degrees (the degrees add up to 180). We can also see that this is a 30-60-90. We can see that the side x, through the identity (you can find 30-60-90 identity online), we see that the side x is . However, it is also asking us to simplify this, so we multiply the top and bottom by and get
Answer:
A = 49 in^2
Step-by-step explanation:
The perimeter of a square is found by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want to find the area
A = s^2 where s is the side length
A = 7^2
A = 7^2
A = 49 in^2
The LCD of 1/2 and 5/6 is equal to the LCM of 2 and 6.
Multiples of 2 and 6
2: 2,4,6
6: 6,12,18
As you can see, the first number in both lines are 6.
