Answer:
Your answer would be 26.64cm.
A step-by-step explanation for you, peabrain:
For all four sides:
1.8cm x 2.7cm = 4.86cm
4.8cm x 4 sides = 19.44cm
For the top and bottom:
1.8cm x 1.8cm = 3.6
3.6cm x 2 sides = 7.2cm
For the complete LSA (lateral surface area):
19.44 + 7.2cm = 26.64cm
Do not forget to round, if that is in your homework instructions :-)!
Answer:
Is an acute triangle
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to

we have
G(7,3), H(9, 0), I(5, -1)
step 1
Find the distance GH
substitute in the formula



step 2
Find the distance IH
substitute in the formula



step 3
Find the distance GI
substitute in the formula



step 4
Verify what type of triangle is the polygon
we know that
If applying the Pythagoras Theorem
----> is a right triangle
----> is an obtuse triangle
----> is an acute triangle
where
c is the greater side
we have



substitute


therefore

Is an acute triangle
N+3=7. To find n, you need to have it by itself, so you can do that by subtracting 3 on both sides, so it would look like: n+3-3=7-3. Then you have n=4.
