AC=4+4.5

=8.5

AC=AD (BOTH ARE RADIUS OF A SAME CIRCLE)

SO AD=8.5

NOW APPLY PYTHAGORAS ,

TAKE BD/2 AS X

X²+4²=8.5²

X²=72.25-16

X²=56.25

X =√56.25

X =7.5

BD/2=X

BD=2X

=2×7.5

BD=15

Lauren save $84 more than Fiona. 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving. How much did Lauren and

muminat

Answer:

Lauren's saving=$180

Fiona's saving=$96

Step-by-step explanation:

Let the saving's of fiona be x

Now given that the savings of lauren is $84 more than fiona which means the saving's of lauren is x+84

Given 1 fifth Of Lauren's saving was the same as 3 eights of fiona's Saving

$\frac{1}{5}(lauren's saving)=\frac{3}{8}(fiona's saving)$

$\frac{1}{5}(x+84)=\frac{3}{8}(x)$

$8x+672=15x$

$7x=672\\x=96$

Therefore the saving's of fiona is $96 and the saving's of Lauren's is 96+84=$180

Answer:

Step-by-step explanation:

If you put 4 with another 4 the total is 8. The two lines must be greater than the third. Equal is not good enough.

The other lengths will produce triangles with 4 and 8. Any 2 will be greater than the third.
