Answer: 180, 185, & 190
<u>Step-by-step explanation:</u>
1st #: 5x
2nd #: 5(x + 1)
3rd #: 5(x + 2)
1st # + 2nd # + 3rd # = sum
5x + 5(x + 1) + 5(x + 2) = 555
15x + 15 = 555
15x = 540
x = 36
1st #: 5x = 5(36) = 180
2nd #: 5(x + 1) = 5(36 + 1) = 185
3rd #: 5(x + 2) = 5(36 + 2) = 190
Using cosine, we can find the hypotenuse by using the formula below;
hypotenuse = adjacent / cos ∅
<h3 /><h3 /><h3>Trigonometric ratios:</h3>
- Trigonometric ratios are ratios of sides of a right angled triangle.
- The simplest ratios are cosine, sine and tangent.
Using cosine, the hypotenuse side can be solved as follows:
cosine ∅ = adjacent / hypotenuse
cross multiply
hypotenuse cos ∅ = adjacent
divide both sides by cos ∅
hypotenuse cos ∅ / cos ∅ = adjacent / cos ∅
Therefore,
hypotenuse = adjacent / cos ∅
