The angle is 16 degrees or 164 degrees.
Any triangle that is not a right triangle is said to be oblique. There are two types of triangles: acute triangles, in which all three angles are less than right angles, and obtuse triangles (one of the three angles is greater than a right angle). Actually, right triangles could equally well be included in the category of "oblique triangles" for trigonometric purposes. In that case, studying oblique triangles is basically studying all triangles.
Given, the area of an oblique triangle which is going to be used as an area of the formula backward to find a missing measure.
We know two side lengths of the triangular region 60 ft and 1 20 ft
Area = 1000-square-foot
A= 1/2*60*120=1000
A=3600=1000
Dividing both sides with 3600,
We get an angle of 16 degrees.
But it is also possible that the area will be the same. If we use this in supplementary angle as well we get,
180-16 = 164 degrees.
