Hitunglah panjang sisi A. QS B. QR

[tex]qs = \sqrt{ {34}^{2} - {16}^{2} } \\ = \sqrt{1156 - 256} \\ = \sqrt{900} \\ = 3 0[/tex]

[tex]QS= \sqrt{PQ^2-PS^2} \\ \\ QS= \sqrt{34^2-16^2}= \sqrt{1156-256}= \sqrt{900}= \sqrt{9\times100}= 3\times10=30\\ \\QR= \sqrt{QS^2-RS^2}\\ \\QR= \sqrt{30^2-25^2}= \sqrt{900-625}= \sqrt{275}= \sqrt{25\times11}=5 \sqrt{11} [/tex]

a. QS = 30 cm
b. QR = 5√11 cm
