The perimeter adds all sides so, 11+7+18+22+14+23.5=95.5 ft. =)

We have to find perimeter of a polygon. The distance around a polygon is called perimeter. So to find perimeter of a polygon we have to add the lengths of all the sides of the polygon.

Here in the problem, the sides of a polygon given,

11ft, 7ft, 18ft, 22ft, 14ft, 23.5ft.

Sum of the lengths of all the sides =

(11+7+18+22+14+23.5) ft

= (18+18+22+14+23.5) ft

= (36+22+14+23.5) ft

= (58+14+23.5) ft

= (72+23.5) ft

= 95.5 ft

We have got the required answer.

The perimeter of the polygon is 95.5 ft.

Two sides of a parallelogram are 65 feet and 87 feet. The measure of the angle between these sides is 52°. Find the area of the
telo118 [61]

Answer:

Area of the parallelogram is approximately 4,456.2 square feet

Step-by-step explanation:

The lengths of the sides of the parallelogram are 65 feet and 87 feet

The measure of the angle between the sides, Y = 52°

The formula for finding the area of a parallelogram is given as follows;

Area of a parallelogram = A·B·sin(Y)

Where;

'A' and 'B' are the length of the parallel sides and 'Y' is the measure of the angle between them

Let 'A' and 'B' represent the 65 feet and the 87 feet respectively, we get;

Area of the parallelogram = 65 ft. × 87 ft. × sin(52°) ≈ 4,456.2 ft.²

Jane made a mistake when writing down a mutliplication , and she multiplied by 54 instead of 45. Her answer was 198 more than it
BARSIC [14]

Answer:

22

Step-by-step explanation:

Given that:

Let number multiplied by 54 = x

Let output = y

x * 54 = y + 198

x * 45 = y

54x = y + 198 - - - (1)

45x = y - - - (2)

Put y = 45x in (1)

54x = 45x + 198

54x - 45x = 198

9x = 198

x = 22

Number multiplied by 54 is 22

Two complementary angles have measures of s and t. if t is less than twice s, which system of linear equations can be used to de
stealth61 [152]

The required expressions are both equations 1 and 2 as shown:

s + t = 90 ......... 1

t .... 2

Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.

According to the question, if two complementary angles have measures of s and t then:

s + t = 90 ......... 1

Twice of 's' is expressed as 2s

If t is less than twice s, this can be expressed as t .... 2

The required expressions are both equations 1 and 2 as shown:

s + t = 90 ......... 1

t .... 2

Does anyone know this one i tried another website but it didn't help me
xz_007 [3.2K]

Answer:

M = -2

Step-by-step explanation:

-17 + 62 = -5 (3M - 3)    Distribute -5 into the parentheses and combine like terms

45 = -15M + 15 Subtract 15 from both sides

30 = -15M    Divide 15 from both sides

M = -2
