Answer:

Ebony need to compare ∠EFG and ∠ONM

Step-by-step explanation:

we know that

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent by ASA

In this problem

EF ≅ ON ----> the included side

To prove congruence by ASA, of triangles EFG and ONM, the corresponding angles of the included side must be congruent

The corresponding angles of the included side are

∠MON and ∠GEF

and

∠EFG and ∠CNM

so

∠MON ≅ ∠GEF  ----> given problem

and

∠EFG ≅ ∠CNM

therefore

Ebony need to compare ∠EFG and ∠ONM

Both angles must be congruent, to prove that triangles EFG and ONM are congruent by ASA

3. Diego drew a scaled version of a Polygon P and labeled it Q.
bogdanovich [222]

Answer:

The scale factor used to go from P to Q is 1/4

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x -----> area of polygon Q

y -----> area of polygon P

z^{2}=\frac{x}{y}

we have

y=72\ units^2

Find the area of polygon Q

Divide the the area of polygon Q in two triangles and three squares

The area of the polygon Q is equal to the area of two triangles plus the area of three squares

see the attached figure N 2

Find the area of triangle 1

A=(1/2)(1)(2)=1\ units^2

Find the area of three squares (A2,A3 and A4)

A=3(1)^2=3\ units^2

Find the area of triangle 5

A=(1/2)(1)(1)=0.5\ units^2

The area of polygon Q is

x=1+3+0.5=4.5\ units^2

Find the scale factor

z^{2}=\frac{x}{y}

we havey=72\ units^2

x=4.5\ units^2

substitute and solve for z

z^{2}=\frac{4.5}{72}

z^{2}=\frac{1}{16}

square root both sides

z=\frac{1}{4}

therefore

The scale factor used to go from P to Q is 1/4

Find the percent of increase or decrease from the first number to the second number. 140 to 84
tresset_1 [31]
We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:

140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)

solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.

Let me know if I can clear anything else up.
