Answer:
2
Step-by-step explanation:
0.50 because the 8 is in the hundredth place and is greater than 5 so you round it up. Then you turn that to a zero because the 8 becomes a 10 but you only use the zero. Then you turn the 4 to a 5 or else the number would be getting smaller and not larger.
It would be helpful if you could post a photo so I can look at the context. Thank you
Answer:
41 sqrt(3)
Step-by-step explanation:
7 sqrt(27) + 5 sqrt(48)
7 sqrt(9*3) + 5 sqrt(16*3)
We know that sqrt(ab) = sqrt(a) * sqrt(b)
7 sqrt(9)sqrt(3) + 5sqrt(16) sqrt(3)
7 * 3 sqrt(3) + 5 *4 sqrt(3)
21 sqrt(3) + 20 sqrt(3)
41 sqrt(3)
The longest side of the triangle lies opposite the largest angle. The shortest side of the triangle lies opposite the smallest angle.
m∠J = 43, m∠L = 84, m∠K = 53
m∠L > m∠K > m∠J therefore KJ > JL > LK
