Question

Using trigonometry what is the value of t

Answer 1

Answer: t≈8.93 units

Explanation:

The cosine of an angle (cos) is the ratio of the adjoining leg of a right triangle to the hypotenuse

Hence,

`\displaystyle\\cos56^0 =(5)/(t) \\`

Multiply both parts of the equation by t(t≠0):

`\displaystyle\\cos56^0(t)=(5)/(t) (t)\\\\t(cos56^0)=5`

Divide both parts of the equation by cos56°:

`\displaystyle\\t=(5)/(cos56^0) \\\\t\approx(5)/(0,56) \\\\t\approx8,93\ units`
