Answer:
60 degrees
Step-by-step explanation:
I believe in the triangle it says 57 degrees so if you round 57 to the nearest tenth you get 60 so it would be 60 degrees
For this case what we must do is use the law of cosines.
We have then:
12 ^ 2 = 6 ^ 2 + 10 ^ 2 - 2 * (6) * (10) cos (x)
Clearing we have:
cos (x) = (12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10))
x = acos ((12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10)))
x = 93.82 degrees
Answer:
The tree is growing in relation to the hill at:
x = 93.82 degrees
The first thing you want to do is get them all into decimal format. You can do this to fractions by dividing the denominator from the numerator. then you organize the decimals into least to greatest.
0.25; 0.479; 0.5; 0.5625
0.25; 23/48; 0.5; 9/16
Hope it helped.
Answer:
3 . . . goes in both boxes
Step-by-step explanation:
Use the distributive property. Remove the common factor to outside parentheses:
3(m +n) = a multiple of 3
The <em><u>correct answer</u></em> is:
They had no placeholding zero.
Explanation:
Our numbering system is one of few known to have a numeral for zero. Mayans did; however, theirs never traveled the world. Babylonians were thought to have a mark for nothing, but it was more for punctuation than numerals. Neither the Romans nor the Egyptians had a number for 0 either.
Zero is key to our system of numbering, as it helps us hold place as well as representing nothing. Without it, it is easier to represent problems in words.
