Answer:
28.246
Step-by-step explanation:
hihi. So you can use the Pythagorean theorem to find any missing sides to a triangle. The equation goes like this: a^2 + b^2 = c^2, where a a and b are the lengths of the 2 bases of the triangle and c is the length of the hypothenuse/longest side to the triangle. Since you know the length of the hypothenuse and of one of the bases you can solve for the last base using the equation which gets you ~8.246. Now, adding that to the other side lengths gets you 28.246 as an approximate perimeter to 3 sig figs
Answer: 18
Step-by-step explanation: -36 / -2 simply
Answer:
Step-by-step explanation:
7/15 + 3/5
I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.
Now all we have to do is add the Numerators tog
7/15 + 9/15ether (the top number)
7/15 +9/15 = 16/15 or 1 1/15
109
21.8x10=218
218 divided by 2 = 109
