Question

h, –6), B(2, 3) and C(–6, k) are the co-ordinates of vertices of a triangle

whose centroid is G (1, 5). Find h.​

Answer 1

Answer:

Blind spot, small portion of the visual field of each eye that corresponds to the position of the optic disk (also known as the optic nerve head) within the retina. There are no photoreceptors (i.e., rods or cones) in the optic disk, and, therefore, there is no image detection in this area.

Answer 2

Appropriate question:-

           

• A(h, - 6), B(2, 3) αnd C(-6, k) αre the co-ordinαtes of vertices of α triαngle   whose centroid is G (1, 5). Find h.

Given: A (h, -6), B(2, 3) αnd C(-6, k) αre the co-ordinαtes of vertices of α triαngle   whose centroid is G (1, 5).

         

To Find: h

$\underline{\dag \; \frak{As \; we \; know \;that :}}$

$\sf {\pink{If~ vertices ~of ~triangle ~are ~(x_1, y_1) , ~(x_2, y_2) ~and ~(x_3, y_3) }}$

$\sf{\pink{ Then, ~centroid ~of ~triangle ~is ~given ~by ~\bigg\{ \cfrac{(x_2 + x_2 + x_3)}{3} , \cfrac{(y_1 + y_2 + y_3)}{3} \bigg\}}}$

     

Therefore,

     

$:\implies \sf G (1, 5) \bigg\{ \cfrac{(h + 2 - 6)}{3} , \cfrac{(-6 + 3 + k)}{3 }\bigg\} \\ \\ \\:\implies \sf \cfrac{(h + 2 - 4)}{3} = 1 \Rightarrow \cfrac{(h - 4)}{3} = 1 \\ \\ \\:\implies \underline{\boxed{\frak{\purple{h = 7}}}} \; \bigstar \\ \\ \\\therefore \underline{\textsf{ \textbf{h = 7 }}}$
