What is the area of a larger regular pentagon if the smaller pentagon has an area of 43.01 in.. The side length of the small pen
frez [133]
The answer is 68.816 inches:

 large pentagon side length / small pentagon side length= ratio
8 / 5 = 1.6 
area of small pentagon x ratio = area of large pentagon
43.01 x 1.6 = 68.816

Find the values of x and y
Zina [86]

Answer:

see below

Step-by-step explanation:

• find x

use tan rule

tan( 60 degrees) = x / 7

tan ( 60 ) x 7 = 12 . 1

x = 12. 1

• find y

you can either use Pythagoras theorem or the sin rule

let's use sin

sin ( 30 ) = 7 / y

y = 14.0

hope this helps, please mark it

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –23x + 1
Finger [1]

Answer:

Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 .

Step-by-step explanation:

Given as :

The equation of one line

y = - 23 x + 12

∵ The equation of line in slope-intercept form is

y = m x + c

where m is the slope of line and c is y-intercept

Now, Compare given line with standard line equation

So, The slope of given line = m = - 23

Now, Again

Other line is passing through point (6 , - 11) and is parallel to given line

so, both the lines are parallel

For parallel line condition , Slope of both lines are equal

Let The slope of other line = M

So, M = m = - 23

Now, Equation of other line passing through point (6 , - 11) and slope - 23 in slope-point form

y - y_1 = M × (x -  x_1)

i.e y - ( - 11) = (- 23) × (x - 6)

Or, y + 11 = - 23 × x + 138

Or, y = - 23 x + 138- 11

i.e y = - 23 x + 127

So, The equation of other line  y = - 23 x + 127

Hence, Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 . Answer
