Answer:
Option D
Step-by-step explanation:
Given f(x) =
g(x) = 2x + 3
Since,
This function is defined for the denominator is not equal to zero.
(2x + 3) ≠ 0
x ≠
Therefore, Option D will be the correct option.
<DSR + <SRD + <RDS = 180° (Angle sum property)
2x + x +3x = 180°
6x = 180°
x = 180°/6
x = 30°
So, <SRD = x = 30°
<RDS = 3x = 3(30°) =90°
<DSR = 2x = 2(30°) = 60°
Hope it helps !
