Answer:
80 square units
Step-by-step explanation:
The area formula refers to a generic triangle ABC in which side lengths 'a' and 'b' are known and angle C is between those sides.
In the given figure, we have known side lengths of 12 and 14, and the angle between them is 72°.
Putting these numbers into the formula, we find the area to be ...
A = (1/2)(12)(14)sin(72°) ≈ 79.9 ≈ 80 . . . . square units
The area of the triangle is about 80 square units.
For this case we have the following inequality:
We must clear "y", so, we have the following steps:
1st step:
Apply distributive property to the right side of the inequality:
2nd step:
We add similar terms:
3rd step:
We add 48 to both sides of the equation:
4th step:
We divide between 22 on both sides:
Thus, the result is given by:
