Solution:

<u>Note that:</u>

Surface area = Area of all faces

<u>Finding the area of the two triangles</u>

2(1/2 x 8 x 6)
=> 8 x 6
=> 48 ft²

<u>Finding the area of rectangle₁</u>

12.6 x 10
=> 126 ft²

<u>Finding the area of rectangle₂</u>

12.6 x 6
=> 75.6 ft²

<u>Finding the area of rectangle₃</u>

12.6 x 8
=> 100.8 ft²

<u>Finding the surface area of the figure</u>

48 + 126 + 75.6 + 100.8
=> 350.4 ft²

PLEASE HELP FAST!!! While bisecting a line segment, Kara has just drawn two arcs, one passing through each endpoint. Which of th

GuDViN [60]

Answer:

Kara should plot points where the arcs intersect above and below the line segment.

Step-by-step explanation:

The bisection of a line segment is the dividing of the line segment into two equal parts. To bisect a line segment, you have place your compass on the endpoints and measure a distance greater than half of the segment. The point of intersection of the arcs both above and below the segment is then joined thereby bisecting the line.

Since Kara has already drawn the two arcs which are greater that half of the length, all Kara needs to do is plot points where the arcs intersect above and below the line segment.

4/7= 5/p. What is P? Pleas solve and show you r work!

vodka [1.7K]

This is a proportion. First you take the numerator times the denominator that is already solved. In this case you will take 5 times 7 and get 35. You then take 35 divided by 4 and get your answer.

Answer:

m<ABC = 116°

m<CDE = 67°

Step-by-step explanation:

✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)

m<ABC = 180 - 64° (Substitution)

m<ABC = 116°

✔️m<CDA = m<CDE + m<ADE (angle addition postulate)

m<CDA = m<CDE + 49°

m<CDA = m<ABC (opposite angles of a parallelogram are congruent)

m<CDE + 49° = 116° (substitution)

m<CDE = 116° - 49° (Substraction property of equality)

m<CDE = 67°

Write the number as a square. 25/169

Vikentia [17]

A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width. The square number will be $\frac{625}{28561}$ .

<h3>What is a square?</h3>

A square is a common polygon with four equal sides and angles that are each 90 degrees in length.

A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.

Many objects can be found in your surroundings that have a square shape. The chessboard, craft sheets, bread slice, picture frame, pizza box, wall clock, etc. are typical instances of this shape.

Specifications of a Square

It has four vertices and four sides.It has equal-length sides.Since all interior angles are equal and right angles, they are all 90° in length.360° is the total of all interior angles.Its two diagonals form a straight angle with one another.

$(\frac{25}{169})^{2} = \frac{625}{28561}$

PLEASE HELP ASAP<br> trigonometry

Alex73 [517]

Answer:

5). x = 11.9°

6). x = 27.2°

Step-by-step explanation:

5). By applying cosine rule in the given triangle,

cos(32)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(32)° = $\frac{x}{14}$

x = 14cos(32)°

x = 11.87

x ≈ 11.9°

6). By applying sine rule in the given triangle,

sin(54°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(54°) = $\frac{22}{x}$

x = $\frac{22}{\text{sin(54)}}$

x = 27.19°

x ≈ 27.2°
