Question

Brainliest to the correct answer ​

Answer 1

Answer:

The length of PQ is 3 Length of QR is 2

Step-by-step explanation:

Answer 2

$sin = \frac{opp}{hyp}$

$\sin(60) = \frac{opp}{4}$

$opp = 3.464101615$

The length of QR is 3.5

//

${c}^{2} - {b}^{2} = {a}^{2}$

${4}^{2} - {3.464101615}^{2} = {4.000.......}^{2}$

$\sqrt{4.000.......} = 2$

The length of PQ is 2
