Okay so you can find the angle by working out the angle in the top right corner of the backwards 'Z' shape. Because there's 180 degrees in a straight line, that top right angle is 180 - 132 = 48.
Now we know that the top right angle is 48, so the angle you're looking for is 48, because they're alternate angles.
That means 3x + 9 = 48. You can find x by rearranging.
3x + 9 = 48
3x = 48 - 9
3x = 39
x = 13.
x is equal to 13.
Answer:
D or B
Explanation:
It is around 77 degrees F
So I would say around 60
A cold front<span> is the transition zone where a </span>cold<span> air mass is replacing a warmer one
</span>T<span>hey move more slowly than warm fronts.</span>
Because other three are characteristics of the cold front and they move faster than warm
so option D is correct
hope it helps
Answer:
Radioactive isotopes are unstable and will decay. ... The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope.
