Answer:
151 degrees
Step-by-step explanation:
∠3 and ∠4 are on a straight line, therefore they are supplementary. This means that they add to 180 degrees.
∠3+∠4=180
We are given the m∠3, it is 29, so we can substitute that in
29+∠4=180
We want to find the m∠4. To do this, we need to get ∠4 by itself. Subtract 29 from both sides, since 29 is being added to ∠4.
29-29+∠4=180-29
∠4=151
So, the m∠4 is 151 degrees
The volume of a cylinder with radius and height is
If the radius is and the height is the formula becomes
Hey there!
Let's say that x-1 is negative:
The first step is to multiply both sides by 2:
Now, move 1 to the right, using the opposite operation:
Divide both sides by -1:
- Note: Since the negative sign is already entered, all you need to enter is 13.
I hope you find my answer helpful.
Good luck!
Have a great day!

Quadratic equation: ax² + bx + c =0
x' = [-b+√(b²-4ac)]/2a and x" = [-b-√(b²-4ac)]/2a
6 = x² – 10x ; x² - 10x -6 =0
(a=1, b= - 10 and c = - 6
x' = [10+√(10²+4(1)(-6)]/2(1) and x" = [10-√(10²+4(1)(-6)]/2(1)
x' =5+√31 and x' = 5-√31
