X-10 + 2x + 1= 90°
you combine like terms:
x+2x= 3x and -10 + 1 = -9
So,
3x - 9 = 90
+9 +9
3x=99
Divide by 3,
x= 33
First Angle: x-10 (plug in 33 for x)
33-10 = 23°
Second Angle: 2x + 1 (plug in 33 for x)
2(33)+1
66+1= 67°
To Check if it’s correct and make a 90° angle:
Add 67° plus 23° which equals 90°
First angle: 23°
Second angle: 67°
Hope that help!!

Woah! Those are some big numbers! Anyways heres my answer: I used the old school way of fuigreing this out but using the pencil and paper I fuigred out 546463+54543 is equal to 601006 and if you were to multiply this by 64 (it took a LONG time for me and quite a few mess ups) its 38464384. Though I gave you the answer I'm just wondering if you could use a calculator because it would be a whole lot easier if you were able to do so.
