A and B are supplementary angles. If A = (5x + 27)° and B = (5x – 7)º, then find the measure of angle A.​
vazorg [7]

Answer:

x=16

(5x + 27)° =5(16)+27=80+27=107

(5x – 7)º= 5(16)-7=80-7=73

Step-by-step explanation

supplementary angle=180

(5x + 27)° +  (5x – 7)º=180

5x+27+5x-7=180

10x+20=180

10x=180-20

10x=160

x=160/10

x=16

(5x + 27)° =5(16)+27=80+27=107

(5x – 7)º= 5(16)-7=80-7=73

107+73=180

5 1/2 <br> -<br> 3 3/4<br> ______
eimsori [14]
So first you want to convert both to have the same denominator.

5 1/2 - 3 3/4

To:

5 2/4 - 3 3/4

Now, to make it easier for me, I would convert both to an improper fraction.

5 2/4 -> 22/4

3 3/4 -> 15/4

So now you can just do,

22/4 - 15/4,

which is just 7/4.

This in mixed number form is 1 3/4.

A regular hexagon is dilated by a scale factor of 75 to create a new hexagon. How does the perimeter of the new hexagon compare
mezya [45]
Let the length of the original hexagon be x:
the perimeter of the hexagon will be:
P=length*number of sides
P=6*x=6x
After the dilation the new length became:
length=scale factor × original length
=75 × x
=75x
thus the new perimeter will be:
6×75x
=450x
hence the new perimeter compared to the old one will be:
450x/6x
=75
the new perimeter is 75 times the old one
