The actual length of the rectangle below is 41 cm. Using the scale drawing below, find the actual width.

Margaret [11]

Okay, so your scale rectangle has a length of l = 8.2 cm. The actual triangle has a length of L = 41 cm. What is the scale factor? You find out by dividing the scale rectangle l from the actual rectangle L.

41 cm / 8.2 cm = 5

The scale factor is 5. That means the actual rectangle is exactly 5 times bigger than the scale rectangle. Now finding the width is easy! If the width of the scale rectangle is 2.1 cm and the scale factor is 5, you just multiply them together!

2.1 cmx 5 = 10.5 cm

The width of the actual rectangle is 10.5 cm! Hope that helps!

Given m || n, find the value of x and<br> y.

Ann [662]

Answer:

x = 41 , y = 139

Step-by-step explanation:

x and 41° are alternate exterior angles and are congruent , so

x = 41

x and y are a linear pair and sum to 180° , that is

x + y = 180

41 + y = 180 ( subtract 41 from both sides )

y = 139

Two sides and an angle (SSA) of a triangle are given. Determine if the given measurements produce one triangle, two triangles, o

Mariana [72]

Answer:

1. c = 28.1, A = 19°, C = 144°

2. c = 2.0, A = 161°, C = 2°

Step-by-step explanation:

In general, if the given angle is not opposite the longest side, there will be two solutions. That is the case here.

Angle A can be found from the law of sines. It will be ...

A = arcsin(a/b·sin(b)) = arcsin(15.73/13.8·sin(17°)) ≈ arcsin(0.333261) ≈ 19.46°

or the supplement of that, 160.54°.

Angle C will be the angle required to make the sum of angles be 180°, either 143.53° or 2.47°.

Side c will be ...

c = b·sin(C)/sin(B) ≈ 47.2002×sin(C)

either 28.053 or 2.032.

There are two possible triangles:

(A, C, c) = (19°, 144°, 28.1) or (161°, 2°, 2.0)
