Answer:
1. Since the angles on the both sides are the same
5x = 100
x = 20
The mistake is that it is absolutely unnecessary to use 180.
2. It is a right angle, which means it would be 90 degrees instead of 180.
3x + 39 = 90
3x + 39 - 39 = 90 - 39
3x = 51
3x = 17
3. The process is wrong
It should be
6x + 2x + 8 = 180
8x + 8 = 180
8x = 172
x = 21.5

Part a you would divide 465 with 49 and then subtract 25 dollars
Hi!
Let's solve both inequalities and check the answer.
y≥x²-4
0≥0²-4
Solve
0≥0-4
0≥-4
This is correct.
y<2x-1
0<2·0-1
Solve
0<0-1
0<-1
This is incorrect.
The answer is D. No. (0,0) satisfies y≥x²-4 but does not satisfy y<2x-1.
Hope this helps! :)
