Answer:
2(-9+3) = -12
x < 3
Step-by-step explanation:
x and y are 5.66 units
The triangle above is a right angled triangle ; and can be solved using trigonometric relation :
Using :
Sin 45 = opposite / hypotenus
Opposite = y ; hypotenus = 8
Sin 45 = y/8
y = sin 45 * 8
y = 5.66 units
Side length x ;
Sin 45 = x / 8
x = sin 45 * 8
x = 5.66 units
