Draw the median and height from the right angle, denoting them m and h, respectively.
If we describe a circle around a triangle, then the center of this circle will lie in the middle of the hypotenuse (by the theorem on the circumscribed circle). Hence:
m = c / 2 = 16/2 = 8
S = (1/2) hc => h = 2S / c = 2 * 32√3 / 16 = 4√3
By definition of the sine:
sinβ = h / m = 4√3 / 8 = √3 / 2
According to the table, we determine that β = 60 °
The angle γ is external to β, therefore γ = 180 ° -β = 180 ° -60 ° = 120 °
A triangle containing an angle γ isosceles, since the median m and half of the hypotenuse are equal (we found out earlier).
Therefore, by the property of an isosceles triangle, the angles at the base are equal (denoted by α).
Then, by the theorem on the sum of the angles of a triangle:
180 ° = γ + α + α
180 ° = 120 ° + 2α
α = 30 ° is one of the desired angles.
We find another desired angle by the same theorem on the angles of a triangle: 180 ° -90 ° -30 ° = 60 °
answer: 30 ° and 60 °
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
