Question

Write the faction ration for each of the following.
If m

Answer 1

`\tan D=(7)/(4),\\\\\sin D=(7)/(8.1), \\\\\cos D=(4)/(8.1), \\\\GI=5.0`

Explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus,

`\text{3. }\\\tan D=(7)/(4),\\\\\sin D=(7)/(8.1), \\\\\cos D=(4)/(8.1),`

`\text{4. }\tan 68^(\circ)=(GI)/(2),\\GI=2\tan68^(\circ)=4.95017370683\approx \boxed{5.0}`
