Answer:
Ф = s/r
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We want to find a formula for the angle Ф in terms of s and r. To do this, start with s = rФ and divide both sides by r:
s rФ
-- = ----
r r
Then Ф = s/r
Answer: LP=15
Step-by-step explanation:
Ok triangle ΔNPL is congruent to ΔNML because they share side LN so side LN = LN
Angle LNP and LNM are right angles so they are congruent.
Sides PN and MN are marked congruent.
With that information we can use SAS to say those triangles are congruent.
This means that side LP=LM
so 10x-5=7x+1
Now we solve

Now we can sub in x to solve LP
10(2)-5
20-5
15

7=45
Step-by-step explanation:
Set them equal to 180. So i started plugging in numbers and subtracting them by 90. Then add it back to the number until i got 180.
