Answer:
x ≈ 25.4 Km
Step-by-step explanation:
Using the tangent ratio in the right triangle on the right
tan54° = =
( multiply both sides by 17 )
17 × tan54° = opp , thus
opp ≈ 23.4
-------------------------------------------
Using the cosine ratio in the right triangle on the left
cos23° = =
( multiply both sides by x )
x × cos23° = 23.4 ( divide both sides by cos23° )
x = ≈ 25. 4 Km ( to the nearest tenth )
Answer:
120°.
Step-by-step explanation:
The sum of all interior angles in a polygon with sides (
,
) is equal to
. (Credit: Mathsisfun.)
The polygon here has 6 sides. . Its interior angles shall add up to
.
Consider the properties of a regular polygon. (Credit: Mathsisfun.)
- All sides in a regular polygon are equal in length.
- All angles in a regular polygon are also equal.
There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be
.
