Hello!
Was there any h/w on Friday. I was ill.
Amal
No, don’t worry Amal – see you Tues and hope you feel better!
how do number 3 ex 6h im stuck
Hi Azaly,
Could you let me know which textbook so I can see the question?
Or maybe write it up on here.
Mr Williams
its book 8A
Okay – you have two rules that you’ll know from the lessons. One for the angles on the inside and another for the angles on the outside.
Which one here?
Then think about using it.
Get back to me when you get stuck. That of course assumes that you will!
Q3 IM MORE STUCK ON
THE ONLY THING IM STUCK ON IS THAT IM NOT SURE IF YOU ADD UP ALL THE ANGLES IN A IRREGULAR PENTAGON YOU GET 540
Right then more help.
The angles are on the inside so use the formula as follows:
Total of the interior angles = (n-2) x 180
where n is the number of sides.
Here there are 5 sides.
Try using the formula and get back to me when you know the total of those angles.
You right because
(5 – 2) x 180
=3 x 180
=540
FIND THE MISSING ANGLE
I DID 120+130+80+90= 420
TO FIND THE MISSING ANGLE I SIMPLY DI 540-420=120 DEGREES
IT LOOKS RIGHT BUT IMNOT SURE IF IT IS
WHAT DO YOU THINK?
OK SILLY ME
“!
OH AND HOW DO YOU EXPLAIN 5 I THINK I NO THE ANSWER BUT DONT NO HOW TO EXPLAIN
Looks right to me.
IM CONFUSE ON 5 ON HOW TO EXPLAIN
Again think about the rules.
Angles on the inside have to add up to 360.
Test it. DEscribe the calculation you’d use in your answer.
OK?
WHAT DOES TESSELLATE MEAN?
Look it up in a dictionary or Google it!
TRIED IT
And?
PS Stop SHOUTING!!!
WHAT DO YOU MEAN
Turn your caps lock off!!
If you google ‘tessellate’ the first hit is a Wikipedia explanation.
thank you
shhhhhhhhhhh!
Thank goodness for that – could hear you from over here! LOL – hope you’re sorted now. Tessellate means tiles that fit together, like on your kitchen floor. But they don’t have to be rectangular
All clear?
hi mr brewin im kinda stuck on the sheet u gave us today plz help
azaly
