Find the value of the trigonometric ratio. Simplify the ratio if possible.

sweet [91]

Step-by-step explanation:

Given that,

BC = 8

Ac = 15

We can find AB using the pythagoas theorem.

$AB=\sqrt{AC^2+BC^2}\\\\=\sqrt{15^2+8^2}\\\\AB=17$

We know that,

$\cos\theta=\dfrac{B}{H}$ , B is base and H is Hypotenuse

$\cosB=\dfrac{8}{17}$

Hence, this is the required solution.

Answer:

$\frac{n^{2} - 1 }{2}$

$\sqrt{29}$

Step-by-step explanation:

Area of triangle=1/2×b×h

$\frac{1}{2} \times (n - 1)(n + 1)$

$\frac{( {n}^{2} + n - n - 1) }{2 }$

$\frac{ {n}^{2} - 1 }{2}$

2. Area of triangle=14

$\frac{ {n}^{2} - 1 }{2} = 14$

${n}^{2} - 1 = 28$

${n}^{2} = 29$

$n = \sqrt{29}$

please rate well and mark BRAINLIEST.
