Answer:
45°
Step-by-step explanation:
Arc YZ is the difference between the given arcs and 360°:
126° +144° +YZ = 360°
YZ = 360° -270° = 90°
The inscribed angle (?) is half the measure of the arc it intercepts:
? = 90°/2
? = 45°
It should be 12cm because
h=height
a=area
b=base
h=a/b we have base 15cm and height 8cm
8cm=a/15cm
8cm*15cm=a
120cm^2=a
we then use the area to find the height with base 10
h=a/b
h=120cm^2/10cm
h=12cm
The answer for 10x - 2y = 20 is y= 5x - 10
The answer for 5x = y + 10 is y = 5x - 10
so basically from this 5x - 10 is the results and 10x - 2y = 20 and 5x = y + 10 are different problems that lead to the same result, hope this helps
