How to use tangent to find the missing leg of a triangle

👉 Learn how to find a missing side length of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enable us to find a missing side length of a right triangle given one of the side lengths and one of the other angles of the right triangle.

If opposite divided by adjacent = tangent ,then tangent times adjacent = opposite. No algebra needed.

Yes, but 3.26 what? What units? If X is the height of a tree for example, what are the units of height? Thx.

@enzoqueijao 3 жыл бұрын

Since it's a theoretical maths exercise, the unit of measurement doesn't matter, just the numbers. If you were trying to find the height of a tree, then it'd depend of the length of the adjacent side. If it was 7 meters, then the opposite would be 3.26 meters

Hello, love your videos but im still confused on my homework. the answers time out after 3 tries and im on my last attempt here. THe first two attempts they got really big numbers like 220 and 105 for the opposite side but when i do it i only get 11.55. my angle is 58.8 and my adjacent is 127 m.
