What is the sum of the interior

Mathematics
1 answer:
GalinKa [24]3 years ago
7 0

Answer:

\boxed {\boxed {\sf 3060 \textdegree}}

Step-by-step explanation:

The sum of a polygon's interior angles is found using this formula:

180 \textdegree (n-2)

where n is the number of sides. This polygon has 19 sides.

n=19

180 \textdegree*(19-2)

180 \textdegree*(17)

3060 \textdegree

The sum of the interior angles is <u>3,060 degrees.</u>

Nter the equation of the line in slope-intercept form.<br><br> Slope is 6, and (1, 3)
kupik [55]

Answer:

The equation in the slope-intercept form will be:

y=6x-3

Step-by-step explanation:

Given

  • slope = m = 6
  • point = (1, 3)

As we know that the equation of a line in point-slope form is

y-y_1=m\left(x-x_1\right)

substituting the values m = 6 and point = (1, 3)

y-3=6\left(x-1\right)

Writing the equation in slope-intercept form

y=mx+b

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

y-3=6\left(x-1\right)

add 3 to both sides

y-3+3=6\left(x-1\right)+3

y=6x-3

Therefore, the equation in the slope-intercept form will be:

y=6x-3

Please I need help on this
vampirchik [111]

Answer:

53.13

Step-by-step explanation:

To find the measure of an angle use an inverse trig function.

Sin A = \frac{4}{5} so you can take the inverse to find A sin^{-1}\frac{4}{5} = A.

Use a calculator to calculate the value.

A = 53.13
