Segment ea is an altitude of triangle def. find the area of the triangle. triangle def with altitude ae is shown. point d is at negative 2, 1. point e is at 2, 5. point f is at 6, 1. point a is at 2, 1. 14.5 15 15.5 16

16

Step-by-step explanation:

A=(1/2)bh

A=(1/2)(df)(ea)

A=(1/2)(8)(4)

(D) 16

Step-by-step explanation:

It is given that Segment EA is an altitude of triangle DEF. Point D(-2,1), E(2,5), F(6,1) and A(2,1).

Now, using the distance formula, we have

And

Thus, the area of the triangle is=

=

=

Thus, the area of the triangle is 16 sq units.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
