On the coordinate plane below, Point P is located at (2,-3), and point Q is located at (-4,4).
Semenov [28]

Answer:

Approximately 9 units.

Step-by-step explanation:

To find the distance between two ordered pairs, we can use the distance formula. The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Let (2,-3) be x₁ and y₁ respectively, and let (-4,4) be x₂ and y₂, respectively.

d=\sqrt{(-4-2)^2+(4--3)^2} \\d=\sqrt{(-6)^2+(7)^2} \\d=\sqrt{36+49} \\d=\sqrt{85}\approx9

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.
