It is 115 degres
BE is a diameter, so it equals 180 degrees
You have to find angle A, because the angle A will equal the arc measure of BC
In order to find A, you need to subtract 40 and 25 from 180
180-40-25=115
The measure of arc BC is 115 degrees
hope this helps:))

Arc BC = 180 - ( 40 + 25) = 180 - 65 = 115

What is the length of leg s of the triangle below?

Phoenix [80]

Answer:

option A

Step-by-step explanation:

take 45 degree as reference angle

using sin rule

sin 45 = opposite / hypotenuse

$\frac{1}{\sqrt{2} }$ = s/ $8\sqrt{2}$
