The heron formula is given by:
A = root ((s) * (s-a) * (s-b) * (s-c))
Where,
s = (a + b + c) / 2
We must calculate the third side of the triangle:
a + b + c = 50
Substituting:
22 + 13 + c = 50
Clearing c we have:
c = 50-22-13
c = 15
Substituting the values in the formula we have:
s = (22 + 13 + 15) / 2
s = 25
Then, the area will be:
A = root ((25) * (25-22) * (25-13) * (25-15))
A = 94.86832981
Rounding off we have:
A = 95 in ^ 2
Answer:
the area of triangle RST is:
A = 95 in ^ 2
Answer:
70
Step-by-step explanation:
Answer: it will be 48 in 4 years.
Step-by-step explanation: If it’s triples every 6 months that mean times 3 so 2 times 3 is 6 and since there are 12 months you can also do times 6 so 2 times 6 is 12 . And it’s 4 years so 12 times 4 is 48
A. You can remember which axis is which by Y-axis is the vertical one (Y to the sky) and X- axis is horizontal. it's not C because you don't have a second point. It's not (0,4) it's just 4.
