Answer:
4/25
Step-by-step explanation:
12 divided by 3
72 divided by 3
Greatest Common Divisor:
3
So 12/72 simplifed would be 4/25 and the GCD would be 3.

Since all circles are similar to each other. Such as the radius always being half of the diameter. The ratio between the diameter and the circumference being pi, etc., we have plenty of information to calculate C, d, and r for both circles.
C/C' = 0.75 was given to us. So we know that d/d' is also 0.75. So let's write that equation and solve for d'
d/d' = 0.75
6.0/d' = 0.75
6.0 = 0.75d'
6.0/0.75 = d'
8 = d'
And r' will be half of d', so 8/2 = 4. Therefore r' = 4.</span>

Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>
The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69
