Answer:
12/13
Step-by-step explanation:
sin can be remembered by opposite over hypotenuse.
the length of the side opposite to angle B is 12, and the hypotenuse is 13. therefore, sin B will be 12/13.
Answer:
<h2>The ratios will be equal to the scale factor.</h2>
Step-by-step explanation:
Dilation transforms an image to a different size.
In Dilation, the shape of the image remain same, but the size of the figure change as per the scale of the Dilation.
As per example, if the scale factor of Dilation is 2, then the area of the dilated figure =
.
Similarly, the sides increase or decrease as per the scale factor.

Answer:
79 electrons
Step-by-step explanation:
If it has 79 protons it will have a total proton charge of 79 so tho make the charge zero we need to add (79) electrons .Mathematically (1*79)+(-1*79)=0
