Step-by-step explanation:

ok wait..................

Answer 2

$\:\: \underline{\underline{\bf{\large\mathfrak\red{~~Solution~1~}}}}$

•sin3∅=cos(∅-6°)

=>cos(90°-3∅)=cos(∅-6°)

=>90°-3∅=∅-6°

=>4∅=96°

=>∅=24°

$\:\: \underline{\underline{\bf{\large\mathfrak\red{~~Solution~2~}}}}$

the distance between the points P(-6,7)and(-1,-5) is

$\sqrt{( - 6 + 1) {}^{2} + (7 + 5) {}^{2} } \\ = \sqrt{5 {}^{2} + 12 {}^{2} } \\ = \sqrt{25 + 144} \\ = \sqrt{169} \\ = 13 \: \: unit$

Hope this helps you...
