Answer: 12+8.2n
Step-by-step explanation: Your basically adding 12 to 8.2 times n.
Answer:
mYW = 151°
Step-by-step explanation:
∠XWY is an inscribed angle because it has a vertex on the circle. This means that m∠XWY is half of the arc it intercepts, which is XY. We can model the situation using an equation:
m∠XWY = mXY / 2
37° = mXY / 2
mXY = 74°
All arcs in a circle add up to 360°. Because of this, we can say:
mXY + mYW + mWX = 360°
74° + mYW + 135° = 360°
209° + mYW = 360°
mYW = 151°
Answer:
113.04 cm^2
Step-by-step explanation:
To find the area, you do radius squared, multiplied by 
Radius is half of the diameter. 12/2 is 6
6^2×3.14=113.1
12 de 24 seria
12÷24 = 0.5
0.5=
50% entonces 12 de 24 es 50%
igual con 18 de 20
18÷20= 0.9
0.9=
90% entonces 18 de 20 es 90%
