Answer:

Step-by-step explanation:

(hypotenuse)² = (adjacent)² + (opposite)²

(opposite)² = (hypotenuse)² - (adjacent)²

(adjacent)² = (hypotenuse)² - (opposite)²

up row

1) x² = 9² + 7² = 81 + 49 = 130

x = 11.4 cm

2) x² = 6² + 4² = 36 + 16 = 52

x = 7.2

3) x² = 4.3² + 7.7² = 18.49 + 59.29 = 77.78

x = 8.8 cm

Down row

1) x² = 7² - 3² = 49 -9 = 40

x = 6.3 cm

2) x² = 6.4² - 2.9² = 40.96 + 8.41 = 49.37

x= 7.02 cm

3) x² = 7.2² - 5.3² = 51.84 - 28.09 = 23.75

x = 4.9 cm

Step-by-step explanation:

P( three in favor of FA)

Select 3 out of 6 FA supporters then select 2 out of 5 FB supportive judges

$=\frac{^{6}_{C_{3}}\times ^{5}_{C_{2}}}{^{11}_{C_{5}}}\\\\=\frac{\frac{6!}{3!(6-3)!}\times \frac{5!}{2!(5-2)!}}{\frac{11!}{5!(11-5)!}}\\\\=\frac{\frac{6!}{3! \times 3!}\times \frac{5!}{2! \times 3!}}{\frac{11!}{5! \times 6!}}\\\\=\frac{\frac{6 \times 5 \times 4 \times 3!}{3 \times 2 \times 1\times 3!}\times \frac{5 \times 4 \times 3!}{2 \times 1 \times 3!}}{\frac{11 \times10 \times 9 \times 8 \times 7 \times 6! }{5 \times 4 \times 3 \times 2 \times 1 \times 6!}}\\\\$

$=\frac{ (5 \times 4) \times(5 \times 2)}{(11 \times 3 \times 2 \times 7 )}\\\\=\frac{ 20 \times 10 }{(11 \times 42)}\\\\=\frac{ 200 }{462}\\\\=\frac{100 }{231}\\\\=0.4329$
