Consider a triangle abc right angled at b such that bac=2×acb. specify the nature of this triangle?

Step-by-step explanation:

ABC right angled at B such that

BAC=2×ACB.

Let ACB = x

BAC = 2x

ABC = 90°

And the sum of angle in a triangle is 180°

:- x + 2x + 90° = 180°

Collecting like terms

3x = 180° - 90°

3x = 90°

x = 90/3

x = 30°

Angle ACB = x = 30°

Angle BAC = 2x = 2×30° = 60°

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
