Answer:
AC = 18.1 cm
Step-by-step explanation:
Construct a line from point B perpendicular to the line AD and mark it as E on line AD. Now you have a right triangle ABE with AB = 16 cm and AE = AD - BC
so AE = 11 cm - 4 cm = 7 cm
You can find BE by using Pythagorean theorem
BE^2 = AB^2 - AE^2
BE^2 = 16^2 - 7^2
BE^2 = 256 - 49
BE^2 = 207
BE = 14.4 cm
Draw a line from A to C, you have a right triangle ACD with AD = 11cm and CD = BE = 14.4 cm
Using Pythagorean theorem
AC^2 = AD^2 + CD^2
AC^2 = 11^2 + 207
AC^2 = 121 + 207
AC^2 = 328
AC = 18.1 cm

Answer:
<h2>3 and 7</h2>
Step-by-step explanation:
When x=3 and x=7, the outcome of f(x) and g(x) are the same, 4 and 10 respectively. That means at the value of 3, f(x)=g(x), and at the value of x=7, f(x)=g(x).
Answer:
Step-by-step explanation:
Complementary angles are two angles that add up to 90°.
We know the measurements of m∠ZA and m∠ZB, so their angle measures will add to 90°.
Let's simplify this equation so we have x on one side of the equation.
Now that we know the value of , we can substitute it inside the equation for m∠ZB ()
