Just did this one! The answer is 41/200 :)
Explication: 2*1/10=0.2
5*1/1000=0.005
0.2+0.005=2.05 (I think)
So the answer is 41/200! (Btw I was confirmed correct!) :)

21, 28, and 35 are multiples of 7. So you can divide each number by 7 (in other words scaling the triangle down by a scale factor of 7).
It becomes 3,4,5, which is the base Pythagorean triple.
3^2 + 4^2 = 5^2
9 + 16 = 25
122 degrees because you have to add both of them together to get the answer so just turn the negative number into a positive number and answer it like that
The formula to figure out the percentage increase or decrease is:
<span>(new - old) / old * 100% </span>
<span>new = 60 </span>
<span>old = 72 </span>
<span>(60 - 72) / 72 * 100% </span>
<span>-12 / 72 * 100% </span>
<span>= -1/6 * 100% </span>
<span>= -0.1666... * 100% </span>
<span>≈ -16.667% </span>
<span>Because it is negative, that's a decrease. </span>
<span>Answer: </span>
<span>A decrease of about 16.7%</span>
