The x axis is a horizontal line and any horizontal line has a slope of zero.
Answer:
x = 12.3
y = 15.9
Step-by-step explanation:
Apply trigonometric ratio to find x and Reference angle = 51°
Opposite side length = x
Adjacent side length = 10
Hypotensive length = y
✔️To find x, apply TOA:
Tan 51° = Opp/Adj
Tan 51° = x/10
x = Tan 51° × 10
x = 12.3 (nearest tenth)
✔️To find y, apply CAH:
Cos 51° = Adj/Hyp
Cos 51° = 10/y
y × Cos 51° = 10
Divide both sides by Cos 51
y = 10/Cos 51
y = 15.9 (nearest tenth)
Answer:
1.75
Step-by-step explanation:
Since the curtains are going up in .25. We need to add .25 to 1.5.
1.5 + .25 = 1.75
Answer:
a<0.4
Step-by-step explanation:
The given inequality is
10(a+0.50)<9.00
We expand the parenthesis to get:
10*a+10*0.50<9.00
Multiply to get:
10a+5<9.00
Subtract 5 from both sides to get:
10a<9.00-5
This implies that:
10a<4
Divide both sides by 10
a<4/10
a<0.4
