MArishka [77]

Answer:

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC

Step-by-step explanation:

Definition of vertical angles: Each of the pairs of opposite angles made by two intersecting lines are known as vertical angles.

So, in the given figure there are two intersecting lines named as AC and EB

So, the pair of vertical angles are :

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC

Thus these are the pairs of vertical angles in the given figure .

Hence  a pair of vertical angles in the figure are :

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC

A gardener transplanted a plant from an indoor pot to an outdoor garden. After 30 days, the plant's height was 18 centimeters. A
Aliun [14]

Let x is the days and the y is the height of the plant.

Let the change between x and y is linear.

So, the relation between x and y will take the form ⇒ y = ax + b

where a and b are constants.

At x = 30 ⇒ y = 18  ⇒⇒⇒  ∴ 18 = 30 a + b   → (1)

At x = 90 ⇒ y = 29 ⇒⇒⇒  ∴ 29 = 90 a + b   → (2)

solve (1) and (2) to find a and b

subtract (1) from (2)

∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60

substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5

<u>So, the equation which represents the plants growth is</u>

<u>∴ y = (11/60) x + 12.5</u>

A circular walk is 1.5 meters wide, if the outer circumference is 72 meters, what is the inside diameter of the walk?​
sukhopar [10]

9514 1404 393

Answer:

  about 19.92 meters

Step-by-step explanation:

The circumference is ...

  C = πd

  72 m = πd . . . . . for outer diameter d

  d = (72 m)/π

The inner diameter is 3 meters shorter, so is ...

  inner diameter = (72/π) m - 3 m ≈ 19.92 m
