a) π/2 b) π/3 c) 2π/3 D) 4π/5

Answer:

$(a)\ \frac{\pi}{2}$

Step-by-step explanation:

Required

Which of a to d is a quadrantal angle

An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.

Such angles (in degrees) are: 90, 180, 270, etc.

So, we have:

$(a)\ \frac{\pi}{2}$

[Convert to degrees]

$\frac{\pi}{2} = \frac{180}{2}$

$\frac{\pi}{2} = 90$

Hence:

$(a)\ \frac{\pi}{2}$ is a quadrantal angle

<em>The other options are not.</em>

Step-by-step explanation:

x+x+x+x+2.5(2)+3(2)=x+x+2.5+3(3)

4x+5+6=2x+2.5+9

4x+11=2x+11.5

-11 -11

4x=2x+0.5

-2x -2x

2x=0.5
