To answer this, you will start with the scale of 1 in:4 ft. I suggest writing in fraction form -see picture.

Make this equivalent to x:15 ft (also in fraction form).

To set this up as an equation use cross products (multiply the diagonal sides)-see picture.

Then solve the equation by dividing both sides by 4.

Her rotors are 3.75 inches in her drawing.

Answer:

m<1 = 45°  

m<2 = 76°

m<3 = 80°

Step-by-step explanation:

<u>Points to remember</u>

1). Vertically opposite angles are equal

2). Sum of angles of a triangles is 180°

<u>To find the measures of given angles</u>

From the figure we get,

m<1 = 45°   [Vertically opposite angles]

By using angle sum property <2 + 59 + 45 = 180

m<2 = 180 - 104

m<2 = 76°

Also m<1 + m<3 + 55 = 180

m<3 = 180 - (m<1 + 55)

 = 180 - (45 + 55)

 = 180 - 100

m<3 = 80°

Solve x&lt;3 and x≥−1 and write the solution in interval notation. If there is no solution, type ∅ .
bearhunter [10]

Shown in the Figure below

Step-by-step explanation:

In this exercise, we have the following system of inequalities:

x

The word and means intersection, so both inequalities must be true at the same time. We can graph this system as indicated in the figure below. Indeed, there is intersection between -1 and 1. Also, the number -1 is included in the solution because x\geq -1 and this is represented by the closed circle. On the other hand, the number 3 is not included in the solution because x and this is represented by the open circle.
