Answer:
a=30 b=30 c= 75
Step-by-step explanation:
By inferring that all triangles are the same measurments, you can easily knock out A and B since it is the same angle that is labeled 30 degrees.
Now to find C you need to know that all angles of a triangle add up to 180 degrees. You also need to know that both bottom angles are the same angle measurement, indicated by the little circle in the angle.
So, For the middle triangle you can create an equation. 30(which was b) + 2c = 180
Subtract 30 from both sides and you are left with:
2c = 150
Divide by 2 on each side:
c= 75
Answer:
Step-by-step explanation:
Given
square bottom area is 
Suppose x in. is cut from each corner to make a open box with maximum volume
New base area is 
Volume of box
Differentiate V w.r.t x to get maximum volume
Put 
![\left ( 24-x\right )\left [ -2x+24-x\right ]=0](https://tex.z-dn.net/?f=%5Cleft%20%28%2024-x%5Cright%20%29%5Cleft%20%5B%20-2x%2B24-x%5Cright%20%5D%3D0)
![\left ( 24-x\right )\left [ 24-3x\right ]=0](https://tex.z-dn.net/?f=%5Cleft%20%28%2024-x%5Cright%20%29%5Cleft%20%5B%2024-3x%5Cright%20%5D%3D0)
but x=24 is not possible therefore x=8 will yield maximum volume
Two equations are:
Te is time east
Tn is time north
Te + Tn = 5 hours
266Te +196Tn = 1190 is the distance equation
Solve these two equations and
Te = 3 hours and Tn= 2 hours
Answer:
x = 1
Step-by-step explanation:
To solve for a variable, you need to get the variable on one side of the equation, and by itself.
4x + 5 = x + 8
4x = x + 3 --- subtract 5 from both sides
3x = 3 --- subtract x from both sides
x = 1 --- divide both sides by 3
Answer:
N = 2
Step-by-step explanation:
n + 5(n-1) = 7
n + 5n - 5 = 7
6n - 5 = 7
6n = 12
n = 2
