What is the sum of the interior angles

Mathematics
1 answer:
galben [10]3 years ago
7 0

Answer:

The sum of the interior angle is 108°

Step-by-step explanation:

To find the sum of the interior angle, you need this equation:

\frac{180(n-2)}{n} (The variable n represents the number of sides does a shape have).

-Count the sides of the shape:

The following polygon shown, has 5 sides.

-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:

\frac{180(5-2)}{5}

-Then, you solve:

\frac{180(5-2)}{5}

\frac{180(3)}{5}

\frac{540}{5} = 108\textdegree

So, the sum of the interior angle is 108\textdegree.

Isaiah has $7.15 in Dimes and Nickels. He has a total of 91 coins. How many of each coin does he have? Group of answer choices d
yarga [219]

Answer:

Dimes = x = 52

Nickels = y = 39

Step-by-step explanation:

Let

Dimes = x

Nickels = y

x + y = 91 (1)

0.10x + 0.05y = 7.15 (2)

From (1)

x = 91 - y

Substitute x = 91 - y into (2)

0.10x + 0.05y = 7.15

0.10(91 - y) + 0.05y = 7.15

9.10 - 0.10y + 0.05y = 7.15

- 0.10y + 0.05y = 7.15 - 9.10

-0.05y = -1.95

y = -1.95 / 0.05

= 39

Substitute y = 39 into (1)

x + y = 91

x + 39 = 91

x = 91 - 39

x = 52

Dimes = x = 52

Nickels = y = 39

Length = 3 inches

Width = 2 inches

We have to calculate the area of the given space to find out that how much area Kian will work with.

So,

Area = Length*Width\\=2*3\\=6\ in^2

Hence,

Help <br> 7. Given the figure, find the desired measurements
EastWind [94]

Answer:

  m∠F = 66°

  m∠D = 57°

Step-by-step explanation:

It looks like you have ...

  ∠D = ∠E = (4x +1)°

  ∠F = (5x -4)°

The sum of the angles in the triangle is 180°, so we have ...

  2(4x +1) +(5x -4) = 180

  13x -2 = 180

  x = 182/13 = 14

Then the angle measures are ...

  ∠D = ∠E = (4(14) +1)° = 57°

  ∠F = (5(14) -4)° = 66°

__

m∠F = 66°

m∠D = 57°
