First row => 12, 13, 15, 15 15, 16, 16, 19

Second row => 23, 25

Third row => 33, 35, 37, 38, 39

Answer:

Option C is the right answer as figure B is formed when figure A was translated 8 units right and 6 units up.

Step-by-step explanation:

In geometry, translation is a term which is used to describe a function that moves an object or figure a certain distance.

In translation, each and every point of the entity or object must be moved for the same distance in the same direction.

Here are some rules when translation is made on the Coordinate Plane:

  • If the object is moved left and down, the rule would be (x - __, y - __). Here the blanks are the distances moved along each axis.
  • For a translation left and up: (x - __, y + __)
  • For a translation right and down (x + __, y - __)
  • For a translation right and up (x + __, y + __)

So, in the light of above rules and regulation, if observe the diagram as shown in question, figure B is formed after figure A was translated 8 units right and 6 units up.

Therefore, option C is the right answer.

from the top of a building 10m high the angle of depression of a stone lying on the horizontal ground is 60° . calculate the dis
Alja [10]

​Answer:

14.29cm

Step-by-step explanation:

Height of the building=10cm

Angle of depression=60°

We are therefore asked to find the distance from the stone to the

the foot of the building;Therefore we use Tan ratio which is opp/adj;

Let the distance from the stone to the foot of the building be x;

10/x=Tan60°

10/x=1.7/1

We then cross multiply to get 1.7x=10

x=10/1.7

=10*10/1.7*10

=100/17

=14.29cm.
