Answer:

Step-by-step explanation:

we know that the triangle to the center is an isosceles,  so the two angle on the circle of that triangle are the same.   both 41,  so 41*2 =82  

all the way around that isosceles triangle is 180  so

180-82 = 98

the angle at O is 98°

the arc BC spans 98°

angle 'a'  is 1/2(98°)

a = 49°

If cos theta = -2/5 and tan theta > 0, what is the value of sin theta?
allochka39001 [22]

angle whose cos is 2/5 is 66.42 degrees

The required angle is 180 + 66.42 = 246.42 degrees answer.
