Question

Me podrían ayudar en la 6 y 8 porfis con resolución

Answer 1

PROBLEMA 6

$R = \frac{ \sin^{2}\alpha + \cos {}^{2}θ }{3} \\ R = \frac{( \frac{3}{4}) {}^{2} + ( \frac{6}{8}) {}^{2} }{3} \\ R = \frac{ \frac{9}{16} + \frac{36}{64} }{3} \\ R = \frac{ \frac{9}{8} }{3} \\ R = \frac{3}{8}$

PROBLEMA 7

$\tan(2a + 1) \times \cot(80) = \tan(80) \times \cot(80) \\ 2a + 1 = 80 \\ 2a = 80 - 1 \\ 2a = 79 \\ a = 39.5$

$a + 5 = 39.5 + 5 = 44.5$

PROBLEMA 8

$\sec(a - b + 5) \times \cos(30) = \sec(30) \times \cos(30) \\ a - b + 5 = 30 \\ a - b = 30 - 5 \\ a - b = 25$
