<span>The standard equation of a circle with center (h, k) and radius : r
is (x - h)² + (y - k)² = r².
h=7 k = -2 r = 11
the center is ( 7, -2) and radius 11</span>
No, a triangle cannot have more than one obtuse angle. Obtuse angles are bigger than 90 degrees but smaller than 180 degrees. Pretend we had two obtuse angles both measuring 135 degrees and an acute angle measuring 23 degrees.
135 + 135 + 23 = 293
therefore, it wouldn't be a triangle anymore... a triangle only equals up to 180 degrees.
I hope that helps.
To find out the area of the field, you just need to multiply 80 meters by 120 meters.
80 meters * 120 meters = 9600 meters²
Therefore, the unit of measurement to figure out how much fertilizer is needed to cover the field is meters².
