c^2 < a^2 + b^2 = acute

c^2 > a^2 + b^2 = obtuse

c^2 = a^2 + b^2 = right

15^2 = 225

7^2 + 9^2 = 49 + 81 = 130

c^2 = 225 but a^2 + b^2 = 130

c^2 > a^2 + b^2 so the triangle is an obtuse triangle

Answer:

9, 7, 15 sides would form an obtuse triangle.

In triangle ABC below, sinC=h/a and sinA=h/c. Which of the following combines the two sine ratios into one equation?
LenaWriter [7]

We know:

sin(C)=\frac{h}{a}

and

sin(A)=\frac{h}{c}


These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms of h:

h=a(sin(C))

h=c(sin(A))


Now, because h=h (by the reflexive property), we can write:


a(sin(C))=c(sin(A))


This is our answer, A.
