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.
YOU'RE WELCOME :D

Answer: 0.006813
Step-by-step explanation:
<u>Your question:</u> The amount of water leaking from a water tank can be modeled with the function f(x) = −x3 − 10x2 − x + 120, where x measures the number of minutes since the leak began and f(x) measures the volume of the tank. During what time period is there water in the tank? (0, 3) (0, 3]
(0, 3) is the best answer
Answer:
The 40 ounce jar is cheaper
Step-by-step explanation:
how i did this was divide 6.00 by 30 to get 0.2 cents per ounce then 7.20 divided by 40 to get 0.18 cents per ounce so the 40 ounce jar would be cheaper, hope this helps.
