Answer:

8.6 to the nearest tenth.

Step-by-step explanation:

Using the distance formula d =  √ [(y2 - y1)^2 + (x2 - x1)^2] where (x1, y1) and (x2, y2) are the two endpoints.

= √ (4 - -3)^2 + (-3-2)^2

= √(49 + 25)

= 8.60

One angle of a triangle is twice as large as another. The measure of the third angle is 60° more than that of the smallest angle
Naddik [55]

Answer:

The measure of the smallest angle is 30º

Step-by-step explanation:

Let the angles be:

x \to the first angle (the smallest)

y \to the second angle

z \to the third angle

So, we have:

y = 2x

z=x + 60

Required

Find x

The angles in a triangle is:

x + y +z = 180

Substitute values for y and z

x + 2x +x + 60 = 180

4x + 60 = 180

Collect like terms

4x = 180-60

4x = 120

Divide by 4

x = 30

An architect is recreating the blueprint for a deck with an existing scale factor of 1in.=2ft. Using 12in by 8in. The architect
NemiM [27]

Answer:

New scale factor is 1 inch = 3 ft.

New width of the blueprint = (16/3) inches = 5.3333 inches

Step-by-step explanation:

Initial scale factor is 1 inch = 2 ft

And the architect draws a blueprint of 12 inches by 8 inches.

Converting to real life scale using 1 inch = 2 ft

Length = 12 inches = 12 × 2 ft = 24 ft

Width = 8 inches = 8 × 2 ft = 16 ft.

New scale factor turns the length to 8 inches

Scale factor = (length in the drawing)/(real life length)

Scale factor = (8 inches)/(24 ft) = (1 inch)/(3 ft)

Hence, new scale factor is 1 inch = 3 ft.

New width of the blue print

3 ft in real life = 1 inch on paper

16 ft in real life = (16/3) inches on paper

New width of the blueprint = (16/3) inches = 5.333 inches
