Answer:

20 5/8 or 165/8

Step-by-step explanation:

1 and 1/4 is equal to 5/4 as an improper fraction.

15 and 1/2 is equal to 31/2 as an improper fraction.

"of" means multiplication.

As a result, we can do 5/4 times 31/2, which equals 165/8 or 20 5/8.

Answer:

$h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.$

$JP=5\sqrt{3}\ cm$

Step-by-step explanation:

Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.

Since EP⊥IJ, then segment JP is the height of the triangle EOJ.

The height of the equilateral triangle can be found using formula

$h=\dfrac{a\sqrt{3}}{2},$

where a is the side length.

So,

$h=\dfrac{10\sqrt{3}}{2}=5\sqrt{3}\ cm.$

Therefore JP is 5√3 cm
