i have a question in math
(( distance between two points ))
the vertices of a right triangle are S(-2,-2), T(10,-2), and R(4,5). find the area of the triangle.
please in detales .. thank u
first of all, your triangle is not right-angled.
The slopes are 7/6, -7/6 and zero
None of these are negative reciprocals of each other, a condition for a right angle.
But the area is easy to find
Clearly the base ST = 12 units and the height from R to ST is 7
So the area = 1/2 x 12 x 7
= 42 units^2
can u explain how u get the height ?
