Find the measure of /_ MFZ

marshall27 [118]

Given:

$MZ\cong PZ$

$m\angle MFZ=(x+9)^\circ$

$m\angle PFZ=(2x-1)^\circ$

To find:

The measure of angle MFZ.

Solution:

In triangles MFZ and PFZ,

$m\angle FMZ\cong \angle FPZ$ (Right angle)

$MZ\cong PZ$ (Given)

$FZ\cong FZ$ (Common side)

$\Delta MFZ\cong \Delta PFZ$ (HL congruent postulate)

$\angle MFZ\cong \angle PFZ$ (CPCTC)

$m\angle MFZ=m\angle PFZ$

$x+9=2x-1$

$9+1=2x-x$

$10=x$

The value of x is 10.

The measure of angle MFZ is:

$m\angle MFZ=(x+9)^\circ$

$m\angle MFZ=(10+9)^\circ$

$m\angle MFZ=19^\circ$

Therefore, the measure of angle MFZ is 19 degrees.

6. Protein bars come in a 4-pack box or 12-pack

cricket20 [7]

Answer:

The 12 pack has a better value.

Step-by-step explanation:

1. create a ratio table.

you want to know how much the 4 pack would cost if it was a 12 pack.

you can see the ratio table in the picture above.

As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.

Then, compare 23.04 to 22.32.

In conclusion, the 12 pack has a better value.
