Answer:
B. 54
Explanation:
Take 72 from 180.
180 - 72 = 108.
Since there are two y's AND they're congruent, divide 108 by two and get 54.
I believe it should be ∆LKD because the parts should correspond with each other. D is a right angle in the first triangle and appears in the middle, so since K is the right angle of the second, it should also go in the middle.
I believe this is proven by HL because both hypotenuses are congruent, as is a pair of legs, and they are both right triangles.
For me, I know that this answer would be greater than 10 because for a fact, 621 and 59 aren't just perfect multiples of 10. But I don't know, because all humans don't really think alike. So, your teacher might say this doesn't work. Then in that case, I am very sorry. :0
But in any case, I hope this helps and have a good night! :D
Answer:
Significant Figures are the figures in a number that are meaningful and are digits with no zeros. Those zeros can be traced in a number like <em><u>“</u></em><em><u>3</u></em><em><u>2</u></em><em><u>0</u></em><em><u>”</u></em>, or <em><u>“</u></em><em><u>5</u></em><em><u>6</u></em><em><u>7</u></em><em><u>0</u></em><em><u>.</u></em><em><u>0</u></em><em><u>0</u></em><em><u>4</u></em><em><u>5</u></em><em><u>”</u></em>. Those zeros are not counted when counting the significant figures.
I hope you understand.
