Answer:
It is given that in triangle XYZ, XY = 13, YZ=20, and XZ=25.Using the law of cosines, we have
CosC=\frac{a^2+b^2-c^2}{2ab}
cosZ=\frac{(YZ)^2+(XZ)^2-(XY)^2}{2(YZ)(XZ)}
CosZ=\frac{(20)^2+(25)^2-(13)^2}{2(20)(25)}
CosZ=\frac{400+625-169}{1000}
CosZ=\frac{856}{1000}
CosZ=0.856
Z=cos^{-1}(0.856)
Z=37.13^{\circ}

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10.
Answer:
Step-by-step explanation:
So if you are 38 inches tall, you can ride four rides at Hollywood Studios. If you are 35 inches but not 38 inches, you can only ride two rides at Hollywood Studios. At 48 inches / 122 cm, you can ride all 49 rides at Walt Disney World. If you're under 32 inches / 82 centimeters you can ride 28 rides, or 57%.
