Answer:
1080 m^2 Don't submit m^2 in your answer.
Step-by-step explanation:
Givens
The catch is to find h
To do that, use a^2 + b^2 = c^2
a b and c are in the same 1/2 triangle.
a = 48/2 = 24 m
b = h = ?
c = 51 meters
Solution
a^2 + b^2 = 51^2 Substitute for b^2 = h^2
24^2 + h^2 = 51^2 Expand 24^2 and 51^2
576 + h^2 = 2601 Subtract 576 from both sides
h^2 = 2601 - 576
h^2 = 2025 Take the square root of both sides
h = 45
Area
Area = 1/2 b * h
Area = 1/2 48 * 45
Area = 1080
Remark
Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.
To find the area, you need to use all of 48 because 48 is the full length of the base.
They could be 28 + 29 + 30
Answer:
The answer to your question is c = 20
Step-by-step explanation:
Data
a = 15
j = 24
k = 32
c = ?
Process
Use proportions to solve this problem. Compare the small triangle and the large triangle.
1.- Proportion of the small triangle
c/15
2.- Proportion of the large triangle
k/j
3.- Equal but terms and solve for c
c/15 = k/j
-Substitution
c / 15 = 32/24
c = 32(15)/24
-Result
c = 20
Answer:Obtuse-angled triangle
Explanation:Triangles can be classified based on the measures of their angles as follows:1- Right-angled triangle: Triangle that has one of its angles = 90°
2- Acute-angled triangle: Triangle that has all of its angles less than 90°
3- Obtuse-angled triangle: Triangle that has one of its angles greater than 90°
The attached image shows an obtuse-angled triangle. We can note that measure ∠B is greater than 90°
Hope this helps :)
If the satellite moves at a speed of 27,000 km p/h, your answer depends on the question.
This could be written in an algebraic expression, such as:
27,000x = S [for S stands for the ultimate speed of the satellite]
Of course, if this is a 3rd grade level question, I highly doubt they have even gotten started to including the alphabet into math.
So, I would suggest plugging 4 into X.
To explain this to her, just say that the speed needs to be multiplied by the amount of hours it has traveled. (I got 4 because there is a '4' in the question instead of 'for').
Meaning,
27,000 x 4 = 108,000 km per 4 hours
If her teacher decides to ask why that number, have her explain the question did not make sense so she plugged in a 4 to find an answer to a certain amount of hours.
Hope that helps a bit with the confusion!
