Please help me out for question 17

Welcome to the other MHN solving classes.

Let's see what to do ......

_________________________________

Step (1)

EC bisects BED ;

Thus : BEC = CED

_________________________________

Step (2)

Question told us that CED = 4 x + 1

Thus : BEC = CED = 4 x + 1

_________________________________

Step (3)

AD is a straight line which means its angle size is equal to 180° degrees.

So :

AEB + BEC + CED = 180

( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180

11x + 4x + 4x - 12 + 1 + 1 = 180

19x - 10 = 180

Plus sides 10

19x - 10 + 10 = 180 + 10

19x = 190

Divided sides by 19

So : x = 10°

_________________________________

Step (4)

AEB = 11x - 12

AEB = 11(10) - 12

AEB = 110 - 12

AEB = 98°

******************************************************

BEC = CED = 4x + 1

BEC = CED = 4(10) + 1

BEC = CED = 41°

_________________________________

Step (5)

AEC = AEB + BEC

AEC = 98° + 41°

AEC = 139°

And we're done.....♥️♥️♥️♥️♥️

histogram or dot plot?

step-by-step explanation:

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
