Answer:
a. x =145
b. a = 75 c=75 b= 105
c. y= 115
d. z = 105
Step-by-step explanation:
a. half a circle equals 180 degrees, subtract 35 from 180 gives u the answer
b. full circle equals 360 degrees, angle 105 is congruent to b meaning b is also 105. Leaving us with 150 degrees, divide 150 by 2 giving 75 to both a and c.
c. add 160 and 85 gives us 245 then subtract that from 360 giving us 115.
d. again half a circle equals 180. subtract 75 from 180 gives us 105
