Explanation:
Let's consider that two consecutive positive integers are x & (x + 1).
★According to the given Question.
⟹x² +(x+1)² =365
⟹x² +x² +1+2x=365
⟹2x² +2x² =365−1
⟹2x² +2x−364=0 (Taking 2 common)
⟹x² +x−182=0
Using splitting the Middle term method :
⟹x² + 14x - 13x = 182 =0
⟹x (x + 14) - 13 (x+ 14) =0
⟹(x - 13) (x + 14) =0
⟹x - 13 =0
⟹x - 13
⟹x + 14 = 0
⟹x = -14
★Finding numbers
First number (x) = 13
Second number (13 + 1) = 14
∴ Two positive consecutive numbers are 13 & 14.
Answer:
a) Exterior angle 60 therefore interior angle at that point 180 - 60 = 120
Figure is a hexagon (Internal angles = 12 - 4 right angles or 720 degrees) ?All polygons have exterior angles that sum to 360 degrees. An exterior angle of a polygon is found by "extending" one of the sides and measuring the angle between that extension and the "next" side. As the polygon in question is regular and has exterior angles of 60 degrees, it has 360/60 sides, or 6 sides
