a1 = 51 + (1 -1 ) * 0.8

a1 = 51

a2 = 51 + (2 - 1)*0.8

a2 = 51 + 0.8

a2 = 51.8

a3 = 51 + (3 - 1)*0.8

a3 = 51 + 2*0.8

a3 = 51 + 1.6

a3 = 52.6

a4 = 51 + (4 - 1)*0.8

a4 = 51 + 2.4

a4 = 53.4

the complete question is

WXYZ is a parallelogram. Find the measure of angle Z
Delvig [45]

Given:

The figure of a parallelogram.

To find:

The measure of angle Z.

Solution:

We know that, the consecutive interior angles of a parallelogram are supplementary angles, it means there sum is 180 degrees.

In the given figure angle W and angle Z are supplementary angle. So,

m\angle W+m\angle Z=180^\circ

(18b-11)^\circ+(9b+2)^\circ=180^\circ

(27b-9)^\circ=180^\circ

(27b-9)=180

Adding 9 on both sides, we get

27b=180+9

27b=189

b=\dfrac{189}{27}

b=7

Now,

m\angle Z=(9b+2)^\circ

m\angle Z=(9(7)+2)^\circ

m\angle Z=(63+2)^\circ

m\angle Z=65^\circ

Therefore, the correct option is C.

1: length of arc=(2πr/360)*3π/2
26.4=r*0.081
therefore,. r=26.4/0.081=325.9cm
this is the answer if the given angle was in degree.
if the angle is in radian then,
26.4=r*3π/2
r=5.6 cm
