Answer:

<h3>The actual size of the kitchen is 14 feet by 20 feet.</h3>

Step-by-step explanation:

We are given scale factor of blueprints of a house as 1/4 in : 1 ft.

That is <em>1 inch = 1×4 feet = 4 feet.</em>

The measure of kitchen 3.5 in by 5 in on the blueprints.

Therefore,  actual length of the 3.5 inches kitchen on the blueprint = 3.5 × 4 = 14 feet.

And actual width of the 5 inches kitchen on the blueprint = 5 × 4 = 20 feet.

<h3>Therefore, the actual size of the kitchen is 14 feet by 20 feet.</h3>

Answer:

46.2 square inches

Step-by-step explanation:

A parallelogram is a quadrilateral (4 sided closed figure) with 2 pair of parallel sides.

The diagram shown is a parallelogram.

Top and Bottom are parallel lines,

both sides are parallel lines (left and right).

The area for a parallelogram is given by:

Area = Base * Height

In the given figure, the base is clearly given as 4.2 inches

The height (perpendicular distance from base) is given as 11 inches.

<em><u /></em>

<em><u>So, basically we do not need the 11.7 inches length of side given.</u></em>

<em><u /></em>

Now, lets compute the area:

Area = base * height = 4.2 * 11 = 46.2 square inches

Answer:

she turned 82 degrees.

Step-by-step explanation:

Suppose, the unknown angle is A

Now, we know that according to the sine law ,

the ratio of side of a triangle and the sine value of the angle opposite to that side is same . It says that,

if a triangle has 3 sides a,b and c and 3 angles A,B,and C and they are opposite to the sides respectively then,

a/SinA=b/sinB=c/SinC

check the image below in attachment.

From the diagram at attachment.

here , angle A is required.

given, angle C= 30

side b=89 m and c= 48 m

sin law says a/sinA=b/sinB=c/sinC

first we take , b/sinB=c/sinC

or, 89/sinB= 48/sin30

or, sinB=( 89×0.5)/48 =0.92

or, B=68

we know, in every triangle , the sum of 3 angles of a triangle is 180

then, A+B+C=180

or, A=180-B-C= 180 - ( B+C)

=180-(68+30)

or, A = 82

therefore , the required angle is 82 degree.

she turned 82 degrees.
