What do you need help with
Step-by-step explanation:
For number 24, x is equals to 10. It's given that the two triangles are congruent, meaning the angles are congruent too. So, angle A is equals to angle D. Angle A is equals to x+10 and angle D equals to 2x. So we make the two equations equal to each other, x+10=2x, we subtract x from both sides and we get x=10. Remember to replace x with 10 and solve it. The angle would be 20°
For number 25, it's the same thing but we are using sides this time. We make both equations equal to each other and solve for z. 3z+2=z+6, subtract z from both sides and we get 2z+2=6, now we subtract two from both sides and we are left with 2z=4, we are not done yet. We have to isolate z, so we divide both sides by 2 since z is being multiplied by 2, and we end up with z = 2
Remember to replace z with 2, the side would be 8.
I hope this helps. Sorry for the long answer and being late.

Step-by-step explanation:
<span>Mean -to-MAD ratio is the division of the Mean by the Mean Absolute Deviaion (MAD). For the set 1, mean / MAD is 10.3 / 1. 6 = 6.4375; and for the set 2, Mean / MAD is: 12.7 / 1.5 = 8.467. This is a measure of disperssion of a set of values. MAD is calculated as the sum of the absolute differences of the values and the mean.</span>
