Answer:

Option D

Yes. By AA~

Step-by-step explanation:

Given are two lines JMG and HMK intersecting at M.

To check whether two triangles are similar

Consider the two triangles HMG and JMK

We are going to compare the angles of the two triangles

We have

Angle H = angle K =39 (given)

Angle HMG = Angle JMK (Vertically opposite angles)

Since two angles of a triangle are congruent the third angle also will be congruent

Thus we find that the two triangles have AAA congruence

Hence the two triangles are similar by AA~.

Maggie created this scale drawing of a soccer field, using a scale factor of 1 inch : 12 yards. She wants to make another scale

larisa [96]

The length and width of the new scale drawing is 36 inches and 24 inches respectively.

The given parameters:

Original scale of the soccer field, 1 inch : 12 yards

The original length and width of the soccer field is calculated as follows;

1 inch : 12 yards

original width = 6 x 12 yards = 72 yards
original length = 9 x 12 = 108 yards

For the new scale of 1 inch : 3 yards, the new length and width are represented as;

the new width:

$\frac{1 \ inch}{x} = \frac{3 \ yards}{72 \ yards} \\\\x = 24 \ inches$

the new length:

$\frac{1 \ inch}{x} = \frac{3 \ yards}{108 \ yards} \\\\x = 36\ inches$

Thus, the length and width of the new scale drawing is 36 inches and 24 inches respectively.

What is the inverse of the function f(x) = 2x – 10

BartSMP [9]

Answer:

y = 1/2x +5

Step-by-step explanation:

change f(x) to y

y = 2x - 10

then switch x and y

x = 2y - 10

then solve for y

add 10 to both sides and divide both sides by 2
