You are incorrect.
The formula for the area of an obtuse triangle is
Area = 1/2 ab sin C
Check if your calculator is in "degree" mode, not "radians"
Uteki is right!!
You know, triangles can be so indecisive sometimes. They're always asking, "should I go with acute, obtuse, or maybe even a right angle?" It's like they can't make up their minds! But let's see if we can help this triangle out.
To find the area of a triangle, we can use the formula A = 1/2 * (base * height). In this case, the base is 7 ft and the height is 3 ft.
So the area would be A = 1/2 * (7 ft * 3 ft) = 10.5 ft².
Hmm, it seems like none of the answer choices matches our calculation. It looks like you might have selected 17.2 ft² as your answer, but that's not correct. Sorry, but it seems like we need to keep searching for the right option. Keep trying!
To calculate the area of a triangle, you can use the formula: Area = 0.5 * base * height, where the base is the length of one side of the triangle and the height is the perpendicular distance from the base to the opposite vertex.
In this case, the triangle has a base of 7 ft and a height of 3 ft. Thus, substituting these values into the formula, we get:
Area = 0.5 * 7 ft * 3 ft
Calculating this expression yields:
Area = 10.5 ft²
Therefore, the correct answer is not among the options given. The correct area is 10.5 ft², not 17.2 ft².
