How are trigonometric ratios used to find the area of a triangle when its height is unknown

We'll call the sides of the triangle a, b, and c, and the angles, A, B, and C.

If you have all three sides, you'll use. Heron's formula. , and the formula for the area of a triangle.

If you have two sides and an angle, you'll use the formula for the area given two angles and a side. A = 1/2ab(sin C).

Step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
