ada yang tau ga ? kalo ada tolong kasih tau pls sekalian pakai rumus (pythagoras pada segitiga sik) …​

Materi: Teorema Pythagoras

Penjelasan

a dan b = sisi siku-siku

c = hypotenusa/sisi miring

a^{2} + b^{2} = c^{2}

Penyelesaian

1.

(AC)^{2} + (AB)^{2} = (CB)^{2}

3^{2} + 4^{2} = (CB)^{2}

9 + 16 = (CB)^{2}

CB^{2} = 25

CB = \sqrt{25}

CB = 5

2.

RQ^{2} + RP^{2} = PQ^{2}

RQ^{2} + 5^{2} = 12^{2}

RQ^{2} + 25 = 144

RQ^{2} = 119

RQ = \sqrt{119} = 10,9087121146

3.

ML^{2} + KL^{2} = MK^{2}

8^{2} + KL^{2} = 10^{2}

64 + KL^{2} = 100

KL^{2} = 36

KL = \sqrt{36}

KL = 6
