Answer:
56
Step-by-step explanation:
triangle area: ½×b×h
4×5×½= 10
10×4= 40
4×4=16
40+16=56
Answer: 17 centimeters
Step-by-step explanation:
The perimeter of a triangle is all 3 sides added up
x+y+z=p
Substitute 14 in for x, 18 in for y and 49 in for p
14+18+z=49
Add on the left side
32+z=49
Subtract 32 on both sides
z=17
So, the third side is 17 centimeters
Hope this helps! :)
12.5% because you divide the two and get 0.125 then to convert it to a percent multiply by 100 for get 12.5%
Part I)
The module of vector AB is given by:
lABl = root ((- 3) ^ 2 + (4) ^ 2)
lABl = root (9 + 16)
lABl = root (25)
lABl = 5
Part (ii)
The module of the EF vector is given by:
lEFl = root ((5) ^ 2 + (e) ^ 2)
We have to:
lEFl = 3lABl
Thus:
root ((5) ^ 2 + (e) ^ 2) = 3 * (5)
root ((5) ^ 2 + (e) ^ 2) = 15
Clearing e have:
(5) ^ 2 + (e) ^ 2 = 15 ^ 2
(e) ^ 2 = 15 ^ 2 - 5 ^ 2
e = root (200)
e = root (2 * 100)
e = 10 * root (2)
