Answer:
Right triangle since it has a right angle = 90°
Explanation
Answer:
Step-by-step explanation:
Consider the following figure,
We know that equilateral triangle is a triangle in which in all sides are equal.
So, AB = BC = AC = 1
Also, in equilateral triangle, altitude and median are the same.
As AM is the median, M is the midpoint of BC,
In the figure, AM is a median as well as an altitude.
In ,
Using Pythagoras theorem:
Similarly, in ,
Answer:
3/6 + 3/12 = 49
12
= 41
12
≅ 4.0833333
Step-by-step explanation:
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 12) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 12 = 72. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - twenty-three sixths plus three twelfths = forty-nine twelfths.
The answer is 4589000.
And the reason, is:
The thousands place is the number 9, so you look at the number next to it on the right side, which is the number 2. Is 2 above 5, or over five? Its below five. So since its below five, the nine will stay as a nine but the rest of the numbers on the right side of the nine will become 0's. But if it was a 5 or above, the nine would become a 10. But you cant say 45810000, so you'd have to change the 8 to a 9.
Hope this helps :)
