The sum of the interior angles of a triangle is 180 degrees
2x-9+3x+x+3=180
6x-6=180
6x=186
x=31
A=2(31)-9
A=62-9
A=53
20 because when you do it that way when it is behind the decimal the numbers are always the opposite thousand hundred tens ones . tens hundreds thousands
Answer:

= 1 whole OR 12/12
Answer:
-10x5 + 8x4 - 7x3 - 20x2 - x + 18
Step-by-step explanation:
Answer:
x = 105°
Step-by-step explanation:
Question :

You can use cross multiplication to solve this.
Let us solve now

12 × x = 35 × 36
12x = 1260
Divide both sides by 12.
x = 105°
Hope this helps you :-)
