Step-by-step explanation:
x = 90- 55 = 35
y = 180- x
y= 180 - 35 = 145
z =180- (y +10)
z = 180 - (145 +10)
z = 180-155
z = 25

Description
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

Answer:
C - 2 2/9
Step-by-step explanation:
7 1 /2 x + 3 2/ 3 = −13
Subtract 3 2/3 from each side
7 1 /2 x + 3 2/ 3 - 3 2/3 = −13 - 3 2/3
7 1/2x = -16 2/3
Change each mixed number to an improper fraction
7 1/2 = (2*7 +1)/2 = 15/2
16 2/3 = (3*16+2)/3 = 50/3
15/2 x = -50/3
Multiply each side by 2/15 to isolate x
2/15 * 15/2 x = -50/3 * 2/15
x = -100/45
Simplify
x = -20/9
Change back to a mixed number
9 goes into 20 2 times with 2 left over
x = -2 2/9
