we know that
The <u>perimeter</u> of a<u> triangle</u> is the sum of the three <u>length</u> <u>side</u>
To find the<u> length</u> <u>side</u> calculate the <u>distance</u> between two <u>points</u>
The formula to calculate the <u>distance</u> between to <u>points</u> is equal to
Step 1
Find the <u>distance</u> ZY
substitute the values
Step 2
Find the <u>distance</u> XY
substitute the values
Step 3
Find the <u>perimeter</u> of the <u>triangle</u>
we have
Substitute
therefore
the answer is
Answer:
where
denote arc lengths of two circles
Step-by-step explanation:
Let denote arc lengths of two circles,
denote corresponding radii and
denote the corresponding central angles.
So,
and
This implies and
As each circle has an arc where the measures of the corresponding central angles are the same,
As radius of one circle is twice the radius of the other circle,
