State whether the given measurements determine zero, one, or two triangles. A = 58°, a = 25, b = 28

Step-by-step explanation:

apply sine formula

so third angle=180-(58+72)=180-130=50°

∠C=50°

so one triangle is formed.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
