Given:

To find:
The value of x.
Solution:
We know that, corresponding sides of similar triangles are proportional.
Since,
, therefore

On substituting the values from the figure, we get


On cross multiplication, we get




Therefore, the value of x is 4.
Answer:
44, 46, and 48
Step-by-step explanation:
add them and you should get 138.
Answer:
702
Step-by-step explanation:
multiply 65*40*54
equals 140400
it conversion cm cube is equal to ml
140400/200
it equals 702 cups
Answer:
3 metres
Step-by-step explanation:
If we draw this out, we'll see that there are actually two similar right triangles (see attachment), which means that we can set up a proportion.
The height of the lookout tower corresponds to the height of the wooden column, while the shadow of the lookout tower corresponds to the shadow of the wooden column. We can then write:
(height of lookout tower) / (shadow of tower) = (height of column) / (shadow of column)
16 / 12 = 4 / x , where x is the shadow / unknown we want to find
Cross-multiply:
16x = 48
x = 3
The answer is thus 3 metres.
Answer:
63.
Step-by-step explanation:
49 plus 37 is 86. subtract that by 23 and you get 63.
