Find the sum of the measures of the intereor angles of each convex polygon.
serious [3.7K]

Step-by-step explanation:

To find the sum of the measures of the intereor angles of each convex polygon

we using formula

  • (x - 2)180°
<h3>#4</h3>

we can put the value of x is 54

then,

  • \longrightarrow \:  (54 - 2) \times 180°

  • \longrightarrow \: 52 \times 180°
  • \longrightarrow \: 9360°
<h3>#5</h3>

we can put the value of x is 19

then,

  • \longrightarrow \: (19 - 2) \times 180°
  • \longrightarrow \: 17 \times 180°
  • \longrightarrow \: 3060°

#6

we can put the value of x is 292

then,

  • \longrightarrow \: (292 - 2) \times 180°
  • \longrightarrow \: 290 \times 180°
  • =》 52200°

#7

we can put the value of x is 5

then ,

  • \longrightarrow \: (5 - 2) \times 180°
  • \longrightarrow \: 3 \times 180°
  • =》 540°

Simon drove for 2 1/2 hours to get from his house to the beach. Simon averaged 55 miles per hour on the trip. What is the distan
Sav [38]

Answer:

The distance from Simon's house to the beach is 137.5 miles

Step-by-step explanation:

we know that

The speed is equal to the ratio of the distance and the time

Let

s ----> the speed in mph

x ----> the distance in miles

y ---> the time in hours

s=\frac{x}{y}

we have

s=55\ mi/h

y=2\frac{1}{2}\ h=\frac{2*2+1}{2}=\frac{5}{2}\ h

substitute in the formula and solve for x

55=\frac{x}{(5/2)}

x=(5/2)55\\x=137.5\ mi

Write the equation of the line that is perpendicular to 3x + 7y = 15 and passes through (4, 9)
k0ka [10]

Answer:

7x - 3y = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 7y = 15 into this form

Subtract 3x from both sides

7y = - 3x + 15 ( divide all terms by 7 )

y = - \frac{3}{7} x + \frac{15}{7} ← in slope- intercept form

with slope m = - \frac{3}{7}

Given a line with slope m the the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{3}{7} } = \frac{7}{3}, thus

y = \frac{7}{3} x + c ← is the partial equation of the line

To find c substitute (4, 9) into the partial equation

9 = \frac{28}{3} + c ⇒ c - \frac{1}{3}

y = \frac{7}{3} x - \frac{1}{3} ← in slope- intercept form

Multiply through by 3

3y = 7x - 1 ( subtract 3y from both sides )

0 = 7x - 3y - 1 ( add 1 to both sides )

1 = 7x - 3y, that is

7x - 3y = 1 ← in standard form
