Answer:

m∠C = 108°

Step-by-step explanation:

The sum of the interior angles of a pentagon is 540°. Divide this sum by the number of angles to find the degrees of each one:

540/5 = 108

Answer:

A) 108 degrees

Step-by-step explanation:

regular pentagon means all the inside angles of the pentagon are the same

to find the inside angles of any polygon you can use the formula:

180(n-2)/n=a

where n is number of sides

a is the measure of one of its interior angles

pentagon has 5 sides

= 180((5)-2)/5

=180(3)/5

=540/5

=108

each angle of the regular pentagon is 108 degrees

measure of angle C is 108

Stewart is hiring a plumber to fit his shower. He charges a callout fee of

Marrrta [24]

Answer:

The plumber charges £16.50 per hour. this is how to solve it. You minus the callout fee from the total fee which is £167.00- £18.50=£148.50. So you then divide 148.50 by the amount of hours which is 9 hours. so 148.50÷9 = £16.50

Please help me with my math

Olin [163]

Answer:

x=115⁰

z=27⁰

Step-by-step explanation:

65+x=180 -> Due to same side interior being equal to 180 degrees

x= 115

x = 3z + 34 -> opposite interior being equal

115 = 3z + 34

81 = 3z

divide by 3 on both sides

z=27

A dilation has center at origin. Which of the following is the image of the point p (7/4-5/2) for a scale factor of 1/7

Natalija [7]

Answer:

The image of the point p is $p'(\frac{1}{4},\frac{-5}{14})$ .

Step-by-step explanation:

The center of dilation is origin and the scale factor is $\frac{1}{7}$ .

The coordinates of point p are

$(\frac{7}{4},\frac{-5}{2})$

If k is the scale factor and origin is the center of dilation, then

$(x,y)\rightarrow (kx,ky)$

Since the scale factor is $\frac{1}{7}$ and the origin is the center of dilation, therefore

$(x,y)\rightarrow (\frac{1}{7}x,\frac{1}{7}y)$

The coordinates of image of p are

$p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{7}\times \frac{7}{4},\frac{1}{7}\times \frac{-5}{2})$

$p(\frac{7}{4},\frac{-5}{2})\rightarrow p'(\frac{1}{4},\frac{-5}{14})$

Therefore the image of the point p is $p'(\frac{1}{4},\frac{-5}{14})$ .
