Question

What is the measure of Angle F?

Answer 1

what is the formula relating no of sides to the total degree in a polygon....(n-2)times 180

Answer 2

this is a hexagom...so n = 6 therefore total angle is 4 times 180 that is 520

Answer 3

so when u add up all the inerior angles, your sum should be 520

Answer 4

i still dont get it? theres an equation for F that i dont understand what to do with?

Answer 5

134 +28 +10x - 4 +10x -4 +5x +8 + 5x +8 = 520

Answer 6

i will go over this again

Answer 7

if there are n sides to a polygon, the total sum of the interior angles in (n-2) times 180.. Since our given polygon has 6 sides, n equals 6. Therefore the sum of the interior angles = (6-2) times 180 that is 4 times 180 that is 520

Answer 8

in the given figure some interior angles are given as expressions, but we know that their total sum is 520....so we add up everything and set it equal to 520

Answer 9

and thats how we got the previously typed equation

Answer 10

does it look good till now?

Answer 11

134 +28 + 10x -4 +10x - 4+ 5x + 8+5x +8 =520

Answer 12

so we add the like terms and we get 30x +170 = 520

Answer 13

oh ok i think i sort of get it so u have to get all of the equations together then add them:D

Answer 14

yepp now u subtract 170 from both sides, we get 30 x = 350

Answer 15

or x = 35/3

Answer 16

now ur angle f is 10x -4

Answer 17

plug in the value 35/3 for x

Answer 18

that is 10(35/3) -4

Answer 19

350/3 - 4

Answer 20

(350-12)/3

Answer 21

112.66 hope i didnt make any computing errors

Answer 22

hmmm ok i sort of have the idea in my head:) so after comparing like terms and then subtracting both sides u gett 520?

Answer 23

yepp

Answer 24

so the answer would be 112.66 at the end?

Answer 25

thats what i got....but do check the additions and subtractions again

Answer 26

ok i will:)
