Answer:

An increase of 20%

Step-by-step explanation:

50/100=60/x

Cross Products

50x=6000

Divide 50 by both sides

x  =  120

60 is 120% of 50, so there is a 20% increase

Which statements are true about the regular polygon? Select three options. The sum of the measures of the interior angles is 900
Akimi4 [234]

Answer:

The sum of the measures of the interior angles is 900° is False

Each interior angle measures 108° is True

All of the angles are congruent is True

The polygon is a regular hexagon is False

The sum of the measures of the interior angles is 180(5 – 2)° is True

Step-by-step explanation:

A pentagon is a polygon having five sides and equal angles. We can find the sum of the measures of the interior angles through 180*(n-2) where n = 5(number of sides a polygon has)

180*(5-2)= 180(3)=540°

Now the angles are 540/5 = 108°

This shows that the statement:

The sum of the measures of the interior angles is 900° is False

Each interior angle measures 108° is True

All of the angles are congruent is True

The polygon is a regular hexagon is False

The sum of the measures of the interior angles is 180(5 – 2)° is True ....

The width of the rectangle is 7 feet, and the diagonal length of the rectangle is 16 feet. which measurement is the closest to t
yanalaym [24]

Answer: b. 14ft

Step-by-step explanation:

In the rectangle, the opposite sides are equal. The diagonal divides the rectangle into two equal right angle triangles. The diagonal represents the hypotenuse of both right angle triangles. The length and width represents the opposite and adjacent sides of the right angle triangles.

To determine the length, L of the rectangle, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore,

16² = L² + 7²

256 = L² + 49

L² = 256 - 49 = 207

L = √207

L = 14.38

the closest to the length of this rectangle in feet is

14ft
