Answer 1

Answer: k = -7/2

Step-by-step explanation:

Given,

Coordinates of vertices of sides of a triangle are - (k,0) , (1,1) , (0,3)

Also, area of triangle = 5 sq

By the formula -

1/2 [ k( 1-3 ) + 1(3-0) + 0(0-1) ] = 5

[k (-2) + 3 + 0] = 5 X 2

-2k + 3 = 10

-2k = 10 - 3

-2k = 7

k = -7/2

Answer 2

Ans:- k= -7/2
