Answer:

Option (D)

Step-by-step explanation:

Given quadrilateral in the circle is a cyclic quadrilateral.

By using the property of cyclic quadrilateral,

"Sum of each pair of opposite angles is 180°".

In the given cyclic quadrilateral,

d + 57° = 180°

d = 180 - 57

d = 123°

Similarly, c + 31° = 180°

c = 180° - 31°

c = 149°

Therefore, Option (D) will be the answer.

A triangle pattern is shown below.
iren [92.7K]

Answer:

A) P = 6n + 8

Step-by-step explanation:

Given:

Perimeter of the 1 triangle = 24

Perimeter of the 2 triangle = 30

Perimeter of the 3 triangle = 36

Let's check with option A.

P = 6n + 18, where "n" is the number in the figure.

Plug in n = 1, we get

P = 6(1) + 18

= 6 +18

P = 25 True.

Plug in n =2, we get

P = 6(2) + 18

= 12 +18

P = 30 True.

Plug in n =3, we get

P = 6(3) + 18

P = 18 + 18

P = 36, true.

Therefore, the answer is A. P = 6n + 18

Thank you.
