Question

Find the measure of Angle e?? need major help

Answer 1

First count the number of sides in the polygon How many?

Answer 2

9

Answer 3

9-2=7
7 times 180 right

Answer 4

right now there a formula for finding the total number of angles in a polygon form its number of sides.

if i recall correctly its 180(n - 2)

i'll check that out.

Answer 5

1,260 is the sum

Answer 6

yes thats right
so you now set up an equation

Answer 7

what would it look like?

Answer 8

6x - 1 + 7x + 6 etc = 1260
solve this for x

and angle e = 7x + 9

Answer 9

170 is the answer thanks!

Answer 10

can i ask you another question??

Answer 11

ok

Answer 12

find the value of c.
a. 10
b.5
c.square root 2
d. 10 square root 2

Answer 13

this right angled triangle is also isosceles because the unmarked angle is also 45 degrees.
So the other leg is also 5 sqrt2

you use the pythagoras theorem to solve this

c^2 = (5 sqrt2)^2 + (5 sqrt2)^2

Answer 14

(5 sqrt2)^2 = 5^2 * 2 = ?

Answer 15

10??

Answer 16

the final answer?

Answer 17

c^2 = (5 sqrt2)^2 + (5 sqrt2)^2, does that equal 10?

Answer 18

no
(5 sqrt2)^2 = 5^2 * 2

Answer 19

= 25 8 2 = 50

Answer 20

* thats * not 8

Answer 21

what do you do with the 50 now?

Answer 22

c^2 = 50 + 50

Answer 23

i've assumed you are familiar with the pythagoras theorem

Answer 24

which is 100, and the final answer is c, so would it be 10?

Answer 25

yep

Answer 26

yes a^2 +b^2 = C^2

Answer 27

i have another problem like this with a scalene triangle

Answer 28

ok gtg now
hope this has helped

Answer 29

thank you
