Question

What is the best approximation of the length of segment QR?

Answer 1

From the given diagram we have,

`tan 80=(QR)/(Rs)`

`5.67=(QR)/(2)`

`5.67*2=(QR)/(2) *2` Multiplying 2 to each sides

11.34= QR

So, the length of QR is 11.34 cm

Answer 2

we are given

S=80

RS=2

we can use tangent formula

`tan(S)=(QR)/(RS)`

`tan(80)=(QR)/(2)`

now, we can find QR

`QR=2*tan(80)`

we will get

`QR=11.34cm`...........Answer
