real:shadow
so the person is 1.8m but the shadow is 4m
so
real:shadow=1.8:4
so
1.8:4=?:14
1.8/4=?/14
times both sides by 14
25.2/4=?
6.3=?
the tree is 6.3 m tall
RST is not a right triangle.
<h3>What is a Triangle ?</h3>
A Triangle is a polygon with three sides , three angles and three vertices.
It is given in the question that
triangle RST with coordinates R(2, 3), S(4, 4), and T(5, 0)
It has to be determined that if the triangle is a right angled triangle ,
If we plot the triangle on the coordinate plane , it can be easily seen that the triangle is not a right angled triangle ,
It can also be proved by measuring the length of the sides that if the sum of the squares of the sides is equal to the square of the largest side , then it will be a right triangle or not .
