and like football best.
Swimming
Netball
KEY
represents 2 children
Football
Cricket
4 children like cricket best.
a) Use this information to complete the pictogram
b) Work out the total number of children in Peter's class.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
