Answer:
x=5
Step-by-step explanation:
15/3=5 or 5x3=15
Answer: 2.3
Step-by-step explanation:
=
x
1.8
\cos 40=\frac{1.8}{x}
cos40=
x
1.8
x\cos 40=1.8
xcos40=1.8
Cross multiply.
\frac{x\cos 40}{\cos 40}=\frac{1.8}{\cos 40}
cos40
xcos40
=
cos40
1.8
Divide each side by cos 40.
x=\frac{1.8}{\cos 40}=2.3497\approx 2.3\text{ feet}
x=
cos40
1.8
=2.3497≈2.3 feet

Answer:
12
Step-by-step explanation:
Since it is on a right angle we can equation the sum of both angles to 90:
6x-2+20 = 90
Now we simplify:
6x+18=90
Now we subtract 18 from both sides:
6x+18-18=90-18
Simplify:
6x=72
Now we divide both sides by 6:
6x÷6=72÷6
Simplify:
x = 12
