(4,2) reflected over the y axis is (-4,2)
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 D
Explanation: Knowledge
Answer:
82
Step-by-step explanation:
Answer:
A. 16 :4 and B 28:7
Step-by-step explanation:
The first ratio given for blue to green blocks is 4:1 which means that for every 1 green block, 4 blue blocks are used. So in the table, 16 blue blocks will be used with 4 green blocks so the ratio will be 16:4 which is the same as 4:1. In the second question, 7 green blocks will be used with 7*4 blue blocks,28 blue blocks so the ratio will be 28:7 same as 4:1
