Answer:
6
Step-by-step explanation:
=cos30°
x=
solove for x
x = 6
The area is 254.34 you had to do pi (3.14) x 9 x 9 since 9 is the radius
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12
