Answer:
A) 70.5
Step-by-step explanation:
cos x = adjacent side/ hypotenuse
cos x = 10/ 30
cos x = 0.3
cos 70 = 0.3420
cos 71 = 0.3256
x = 70.5
The center of the circle is (-3, 7)
The middle of the circle is on the line where x is -3, and on the line where y is 7
p=25 degrees
70 and 20+2p are verticle angles, so they are equal
70=20+2p
-20-20
50=2p
/2 /2
25=p
