10:18

Not at all Millie

Anna

10:19

I am stuck on question 27

Mr Warbrick

10:20

Okay, it's slightly tricky

How big are each of the angles I've drawn in if the shapes are equilateral?

millie

10:23

i think it just switched onto a different question

Mr Warbrick

10:23

It moves you on when it thinks you're ready Millie

Anna

10:23

I think I have got it now but thank you anyway

Mr Warbrick

10:23

You're welcome!

Olivia

10:23

Please can I have help on Q22.

Mr Warbrick

10:24

Of course. If angles a and b are both acute then they both must be less than....?

Olivia

10:24

A reflex?

Mr Warbrick

10:24

They must both be less than 90

So if we add them together, they would total less than 180 degrees

Which means that angle c must be....

Kacie

10:25

Can I have help on question 29

Mr Warbrick

10:25

Have you got it now Kacie?

Amber

10:25

Can i have some help on question 30 ?

Mr Warbrick

10:25

Start with 360 - 243

Olivia

10:25

Amber

10:26

117

Mr Warbrick

10:26

Good! So a + b = 117 and b is double a so we can try some numbers

If b was 80 degress for example, a would be 40

But they add up to 120, so it's not that

Olivia

10:27

Is angle C 360 degrees then?

Mr Warbrick

10:27

So, angle c is 360 take away whatever a+b =

So if a+b = less than 180 degrees, then C must be more than 180 degrees :)

Olivia

10:28

Ohhhhh

Amber

10:28

78+39=117 works

Mr Warbrick

10:28

It does, so b is 78 degrees :)

Kacie

10:28

I have not got question 29 yet can I have help x

Mr Warbrick

10:28

Of course.

10:29

The pie chart is 360 degrees. Pepperoni is a third of that so what is one third of 360?

Kacie

10:30

Is it 120

Mr Warbrick

10:30

Good. A quarter like ham. What's a quarter of 360?

Kacie

10:31

oh I know it’s 90
