To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2. First answer, 20^2+30^2=c^2. Solve for c. c=36.06. The second answer, 20^2+b^2=30^2. Solve for b. b=26.36.
Answer:
12
Step-by-step explanation:
a2+b2=c2 since the hypotenuse is 13 you would square it to get 169 and then you would square 5 and get 25 you would subtract 169-25 and get 144 then you would square root that number and get 12 so then your answer is 12 in.
Answer:
Step-by-step explanation
3x-15=2x-10+x
3x-15=3x-10
in this step, problem happens
becoz both side doesnt equal, no ans can be proven
Answer:
3 multiply by 6 multiply by 5
= 90 cm²
Answer:
Side length = 
cm , Height = 
cm , Volume = 
cm³
Step-by-step explanation:
Assume
Side length of base = x
Height of box = y
total material required to construct box = A ( given in question)
So it can be written as
A = x² + 4xy
4xy = A - x²
Volume of box = Area x height
V = x² ₓ y
V = x² ₓ ( 
)
V = 
To find max volume put V' = 0
So taking derivative equation becomes
A = 3 
= 
x = 
put value of x in equation 1
y = 
y = 
y =
So the volume will be
V = × y
Put values of x and y from equation 2 & 3
V = 
V =
