PLEASE HELP DUE IN A FEW MINUTES, LIKE LITERALLY 5 MINUTES, 69 POINTS FOR THE FIRST THREE OT FOUR calculate the magnitude of each of the unknown angles

a. x =145

b. a = 75 c=75

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

Hello!

a: x = 145

b: b = 105 c = 75 a = 75

c: y = 115

d: z = 105 not to sure for question d so put that at your own risk everything else im sure about

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
