Find the missing length of the triangle.
4 yd
12; yd
2
yd

Missing length =

Step-by-step explanation:

By Pythagoras theorem,

Square of the longest length = Sum of square of smaller lengths of the triangle

a² = 152.11 - 16

a² = 136.11

a = √136.11

a = 11.67 Or

Therefore, missing length of the given triangle will measure yd.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
