Question

What is the measure of -- to the nearest hundredth
QR
of a centimeter?

Answer 1

its the measure of QR

Answer 2

sin(angle) = opposite/hypotenuse

sin(49) = QR/PR

sin(49) = QR/12.38

solve for QR

Answer 3

so then 49 is qr?

Answer 4

no

Answer 5

3.957??

Answer 6

im confused lol sry

Answer 7

you need to isolate QR, so how do you do that

Answer 8

`sin(49) = (QR)/(PR)`

`0.7547 = (QR)/12.38`

QR = 12.38 * 0.7547 cm ??

Answer 9

keep going

Answer 10

okay well i did that then i got 9.343186

Answer 11

same here, so congrats

Answer 12

but would i round it?

Answer 13

so QR = 9.34 because you round to the nearest hundredth

Answer 14

nearest hundredth

Answer 15

yeah

Answer 16

oh okay thank you so much

Answer 17
