$\text{Area of triangle} = \dfrac 12 \times PQ \times QR \times \sin \angle PQR \\\\\\\implies 273= \dfrac 12 \times 12.8 \times QR \times \sin 107^{\circ}\\\\\implies 273 = 6.4 \sin 107^{\circ} \times QR\\\\\\\implies QR = \dfrac{273}{6.4 \sin 107^{\circ}} = 44. 606~~ \text{cm}$

Jake ate 1/6 of the cookies at the party if he ate 5 cookies how many cookies were there in all

egoroff_w [7]

If Jake ate 1/6 of the cookies at the party and we know he ate 5 cookies. We must find out how many cookies there are in all.

$\frac{1}{6} = \frac{5}{x}$

Now x here represents how many total cookies are at the party.

We have to simply find out what 1 was multiplied by to get 5.

We can do this by dividing.

5 ÷ 1 = 5

So the numerators (the top numbers) were multiplied by 5. We can do the same to the denominators (the bottom numbers) to get the total number of cookies.

Lets multiply.

6 x 5 = 30

So the total number of cookies is 30

Good Luck! <3
