Answer:
D. 11.8 cm.
Step-by-step explanation:
This is a 30-60-90 triangle, which means that the hypotenuse is 2x, the short leg is x, and the long leg is x
.
In this case, the hypotenuse is 5.
5 / 2 = 2.5. That is the short leg.
The long leg is 2.5 * = 4.330127019.
5 + 2.5 + 4.330127019 = 7.5 + 4.330127019 = 11.83012702, which is about D. 11.8 cm.

Answer:
8 and 2
Step-by-step explanation:
Let x = the smaller number.
Let y = the larger number.
Let the numbers be x and y
x+y = 10 ..............(1)
y= 4x ........(2)
Put value of y into equation 1
x + y = 10
4x + x = 10
5x = 10
Divide both sides by 5
x = 10/5 = 2
Put value of y into equation 2
y= 4x
y= 4(2)
y = 8
Therefore the numbers are 8 and 2
