P(red) first drawn:
20/36=5/9
P(red) second drawn:
19/35
95/315 or 19/63. As a result, the probability that both marbles are red is 19/63. Hope it help!
Answer:
x=8
Step-by-step explanation:
7x-6+60+70=180°
7x-6+130=180°
7x+124=180°
7x=180-124
7x=56
x=56

Opposite angles of a cyclic quadrilateral add up to 180 degrees so m<R = 180-92 = 88 and m < S = 180-92 = 88 degrees also
m< R = m< S Answer
Without knowing what Juan's exact steps were, it's hard to say what he did wrong. The least you could say is that his solution is simply not correct.
4 sin²(<em>θ</em>) - 1 = 0
==> sin²(<em>θ</em>) = 1/4
==> sin(<em>θ</em>) = ±1/√2
==> <em>θ</em> = <em>π</em>/4, 3<em>π</em>/4, 5<em>π</em>/4, 7<em>π</em>/4
