Answer:
x = 96
Step-by-step explanation:
x + x - 5 + x - 11 + x - 8 = 360
4x - 24 = 360
4x = 360 + 24
4x = 384
x = 96
The first thing you should do in this case is to write the expression correctly:
- (1/9) y + (1/3)
Now, we take out common factor (1/9) obtaining:
1/9 (-y + 3)
Let's check:
1/9 (-y + 3)
-1/9y + 3/9
-1/9y + 1/3
OK
Answer:
An expression equivalent is:
1/9 (-y + 3)
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×

= 180° ×
∴ the size of the largest angle = 80°
