Question

If Ø is the smallest angle in a right triangle with side lengths of 3, 4, and 5 units, then what does sin Ø equal ?

Answer 1

Answer:

If θ is the smallest angle in a right triangle with side lengths of 3, 4, and 5 units, then what does sin θ equal ?

SIN(θ) = 3/5

Answer 2

The value of sinθ is equals to 3/5

Assuming a given triangle, the longest side in the right angle triangle is equal to 5, the opposite and adjacent could either be 3 or 4.

Data given;

• hypothenuse = 5
• opposite = 3
• adjacent = 4

Trigonometric Ratio

From trigonometric ratios,

SOHCAHTOA

sinθ = $\frac{opposite}{adjacent}$

This make sinθ = 3/5
