Answer:
x = 12 cm
Step-by-step explanation:
Based on the tangent and secant theorem,
8² = 4(4 + x)
Solve for x
64 = 16 + 4x
Subtract 16 from both sides
64 - 16 = 4x
48 = 4x
Divide both sides by 4
48/4 = 4x/4
12 = x
x = 12
Answer:
c
Step-by-step explanation:
you do 520 divided by two hours
8, because you’re doubling the numbers so 3x2=6 and 4x2=8.
You would subtract 4 from both sides. Then it would be 3n = 3. You would then divide each side by 3. The answer you would get is n = 1.
