Explanation
A regular pentagon has five equal sides and five equal interior angles. To find the measure of each interior angle, we can use the formula (n-2) * 180° / n, where n is the number of sides of the polygon. Plugging in the values, we get (5-2) * 180° / 5 = 3 * 180° / 5 = 540° / 5 = 108°. Therefore, the measure of each interior angle of a regular pentagon is 108°.

Explanation
The statement "Medians exist in which of the following shape/shapes?" implies that we are looking for shapes that have medians. A median is a line segment that connects a vertex of a triangle to the midpoint of the opposite side. In the given options, a trapezoid is the only shape that can have medians. Parallelograms, rhombuses, and squares do not have medians because their sides are not divided into two equal halves. Therefore, the correct answer is trapezoid.

B. 3.5
Explanation
In a trapezoid, the parallel sides are called bases. In this case, AD is one of the bases and BC is the other base. It is given that AD = 14 and BC = 7 + 2x. To find the value of x, we need to equate the bases. By setting AD equal to BC, we have 14 = 7 + 2x. Solving this equation, we get x = 3.5. Therefore, the value of x is 3.5.

### The diagonals in all parallelograms bisect each other

• A.

True

• B.

False

A. True
Explanation
In a parallelogram, the opposite sides are parallel and equal in length. Since the diagonals of a parallelogram connect opposite vertices, they also bisect each other. This means that the point where the diagonals intersect divides each diagonal into two equal halves. Therefore, the statement that the diagonals in all parallelograms bisect each other is true.

Rate this question:

• 36.

### In a rhombus, the diagonals bisect the angles

• A.

True

• B.

False

A. True
Explanation
In a rhombus, the diagonals bisect the angles. This means that each diagonal divides the angle formed by the adjacent sides into two equal parts. This property is true for all rhombuses, making the statement "True" the correct answer.

Rate this question:

• 37.

### The diagonals in all parallelograms are congruent

• A.

True

• B.

False

B. False
Explanation
The statement is false. In parallelograms, the diagonals are not always congruent. While the opposite sides of a parallelogram are always equal in length, the diagonals may have different lengths. The diagonals of a parallelogram only bisect each other, meaning they divide each other into two equal parts, but they are not necessarily congruent. Therefore, the correct answer is false.

Rate this question:

• 38.

### The legs in a trapezoid are always congurent

• A.

True

• B.

False

B. False
Explanation
The given statement is false. In a trapezoid, the legs are not always congruent. The legs of a trapezoid are the two sides that are parallel to each other. However, these legs can have different lengths, which means they are not congruent. Only the two non-parallel sides of a trapezoid, called bases, can be congruent if the trapezoid is an isosceles trapezoid.

Rate this question:

• D.

360

C. (n-2) * 180
Explanation
The equation for the sum of the interior angles of a polygon is (n-2) * 180. This equation is derived from the fact that the sum of the interior angles of any polygon can be found by subtracting 2 from the number of sides (n) and then multiplying the result by 180. This formula holds true for all polygons, regardless of the number of sides.

D. A = 1/2 * h * (b1 + b2)
Explanation
The equation for the area of a trapezoid is A = 1/2 * h * (b1 + b2). This formula calculates the area by taking the average of the lengths of the two parallel bases (b1 and b2) and multiplying it by the height (h) of the trapezoid. The 1/2 factor is included to account for the fact that the trapezoid is a quadrilateral with only one pair of parallel sides.

• C.

2x+43+3x+21=90

• D.

2x+43=90

B. 2x+43=3x+21
Explanation
To solve for x in the parallelogram, we can set up an equation using the given information. The equation 2x+43=3x+21 represents the relationship between the angles in the parallelogram. By subtracting 2x from both sides of the equation, we can isolate the x term. This gives us 43=x+21. By subtracting 21 from both sides, we find that x=22. Therefore, the equation 2x+43=3x+21 can be used to solve for x in the parallelogram.
