R = 3/91 since 3/7 is equal to .42857 and 13 divided by .42857 is 3/91.

The answer would be D) R = 3/91. Here are the steps.

1. divide both sides by 13

2. reduce 3/7 and 13 to 3/7*13

3. reduce 7 * 13 to 91.

* Reduce = Simplify.

siniylev [52]

Step-by-step explanation:

if they are parralel it means gradient is the same

finding equation we find another point which is (x,y)

therefore y - 2/ x - 4 should be equal to 2/3.

y - 2 = 2/3(x - 4)

y - 2 = 2/3x - 8/3

y = 2/3x - 8/3 + 2

The area of triangle PQR is 273 cm. Given that PQ = 12.8cm and PQR = 107°, find QR.

storchak [24]

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