Question

90 POINTS PLEASE HELP Choose one problem below and use trigonometry to solve for the missing side x of the right triangle

Answer 1

x = 13.28

Explanation:

basic trig ratios: using tanФ = opp/adj.

tan(38) = x / 17

x = tan(38) * 17

x = 13.28

The cotangent (cot)

The cotangent is the reciprocal of the tangent. It is the ratio of the adjacent side to the opposite side in a right triangle.

tan(A) = opp/adj = a/b

cot(A) =adj/opp = b/c

Answer 2

`\Huge \boxed{x \approx 13.28}`

`\rule[225]{225}{2}`

Explanation:

The triangle is a right triangle.

We can use trig functions to solve for the problem.

`\sf \displaystyle tan (\theta)=(opposite)/(adjacent)`

`\sf \displaystyle tan (38)=(x)/(17)`

Multiplying both sides by 17.

`\sf \displaystyle 17 \cdot tan (38)=(x)/(17) \cdot 17`

`\sf x= 13.28185565...`

The measure of x is approximately 13.28.
