Find the measure of angle A (please help!!!)
mel-nik [20]

Answer: 41 degrees

Step-by-step explanation:

so, we know that a triangle is 180 degrees. since we know that one angle is 80 degrees, we can subtract that from the equation. now, we are trying to find what X is so that we can find the angle. here is how i did it:

i rewrote it and removed the parentheses.

4x + 1 + 4x + 19 = 100

then, i collected like terms and calculated it.

8x + 20 = 100

then, i moved the constant to the right.

8x = 100 - 20

then, i simply calculated it.

8x = 10

solution: x = 10

so, we just insert X into the angle for A. that gets us 4(10) + 1 = angle A

40 + 1 = angle A, hence angle A = 41 degrees.

The parking lot for a hotel should have 114 parking spaces. If ech row can have 13 parking spaces, then the minimum nukber of ro
MArishka [77]

So @mathmate deleted my comment because "I wasn't explaining my answer" well I did

I clearly stated that you have to make educated guess and I showed how I GOT my answer

so i guess here is my "proper" answer

There is no specific formula for this, so you can make an educated guess

for example:

13*5 = 65 (this isn't right because we need a minimum of 114)

so we continue the guessing

I then next tried

13*9

I got 117,

117 is more than 113

making 9 the minimum amount of rows for the hotel parking lot


there ya go @mathmate is that clear enough?
