5 0

Answer:

x is 30

Step-by-step explanation:

Angles in an equilateral triangle are 60°

Angle form by a radius and a tangent is 90°

90° + 60° + x = 180°

{Sum of angles in a triangle = 180°}

x = 180° - 150°

x = 30°

What is the area of this polygon? Enter your answer in the box. units²
Gemiola [76]

Answer:

The area of the polygon is 39\:units^2

Step-by-step explanation:

Sketch the polygon to obtain the figure in the attachment.

The polygon can then be divided into a rectangle and a triangle.

The area of the polygon

=|VE|\times |DE|+\frac{1}{2}\times |DE|\times |AM|

We use the absolute value method to find the lengths

=|3--2|\times |3--3|+\frac{1}{2}\times|3--3|\times |5-2|

=5\times 6+\frac{1}{2}\times 6\times 2

=30+9

=39\:units^2

What is the value of r, the part of the job that Marina can complete in 1 hour? 0.1 0.4 0.5 0.6
kvv77 [185]
So, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)

if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer

Juan is making a border out of rhombi for his wall. Each rhombus will be connected to the one before it. Each rhombus will be 6
marin [14]

Answer:

Part 1) Area of each Rhombus is 12 square inches.

Part 2) Juan will use 396 square inches of paper.

Step-by-step explanation:

Juan is making a border out of Rhombi for his wall.

Each Rhombus will be 6 inches tall and 4 inches wide.

We can say length of diagonals of Rhombus 6 in and 4 in

Part 1) We need to find the area of each Rhombus whose diagonal 6 in and 4 in.

\text{Formula: Area of Rhombus }=\frac{1}{2}\times d_1\times d_2

\text{Where, }d_1=6\text{in and }d_2=4\ in

\text{Area of Rhombus}=\frac{1}{2}\times 6\times 4\Rightarrow 12\text{ in}^2

Thus, Area of each Rhombus is 12 square inches.

Part 2) If wall is 11 feet.

First we change 11 feet into inches.

1 foot = 12 inches

11 feet = 11 x 12 = 132 in

We are given Rhombus is 4 in wide. Each Rhombus cover 4 in but we need to cover 132 in.

\text{Number of Rhombus need }=\frac{132}{4}\Rightarrow 33

We have found area of one Rhombus is 12 square inches.

We need to find total paper to cover wall = 12 x 33 = 396 square inches.

Thus, Juan will use 396 square inches of paper.
