Given: △ABC, BK=10, AC=30,
1 answer:
Answer:
12 units.
Step-by-step explanation:
Consider right triangle MNO. This triangle is isosceles triangle, because MN = MO. Let NO = 2x units. NO is the hypotenuse in right triangle MNO, then MD = x units (the height in isosceles triangle is also its median and the median drawn to the hypotenuse in the right triangle is half of the hypotenuse).
Triangles NBO and ABC are similar triangles, then
where h is the height of the triangle NBO.
Since BK =10 units and MD = x units, the height h = 10 - x units.
Thus,
Hence, NO = 12 units.

Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider, and
.
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus, and
are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
