How many triangles can I make with side lengths of 15 in, 7 in, and 4 in?

1 answer:

3 0

If those sides can form a triangle, the longest side must be less than the sum of the other 2 sides.

15 is NOT less than (7 + 4) and therefore no triangle can be formed.

Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.

Answer:

x ≈ 11.1

Step-by-step explanation:

Using the sine ratio in the right triangle

sin59° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{13}$ ( multiply both sides by 13 )
