<A = 75degrees

Step-by-step explanation:

From the triangle given;

arcDA + arc AD  + arcBD = 360 degrees

131 + 79 + arcBD = 360

210 + arcBD = 360

arcBD = 360 -210

arcBD = 150 degrees

Since the angle at the vertex <A is half that at the arc BD, hence;

<A = 1/2 arcBD

<A = 1/2 * 150

<A = 75degrees

Hence the measure of angle A s 75degrees

c

step-by-step explanation:

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!
