Answer:
3
Step-by-step explanation:
Insert x = -1 and y = 4 into the first inequality:-
4 <= -(-1) + 4 = 5
so this fits
Its A

Trigonometric ratio</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let b represent the base of the triangle and h the height, hence:
sin(60) = h / 18
h = 15.6 feet
sin(30) = b / 18
b = 9 feet
The area of triangle = (1/2) * b * h = 0.5 * 9 * 15.6 = 70.1 ft²

Answer:
60
Step-by-step explanation:
p = 180 - [ 360 - ( 130 + 110 ) ]
= 180 - [ 360 - 240 ]
= 180 - 120
p = 60
X=13/12
1. Calculate
2.Swap the sides
3. Divide both sides
