Ответ:
GF = ½ RT
Step-by-step explanation:
SG=GR (given)
SF=FT (given)
line GF is a midpoint in triangle RST, so it is therefore ½ the angle parallel to it(viz. RT)
Ответ:
The length of segment joining the endpoints of the arc is![8\ in](/tpl/images/0393/1361/2416e.png)
Step-by-step explanation:
we know that
In the triangle ABC
see the attached figure to better understand the problem
Initially the triangle ABC is an isosceles triangle
Remember that
the sum of the internal angles of triangle must be equal to![180\°](/tpl/images/0393/1361/16306.png)
For this particular case, the isosceles triangle ABC becomes an equilateral triangle, as the three angles are equal to![60\°](/tpl/images/0393/1361/7e33b.png)
The equilateral triangle has three equal sides and tree equal angles
so
Hence
The length of segment joining the endpoints of the arc is![8\ in](/tpl/images/0393/1361/2416e.png)
