Answer:
837,000
Step-by-step explanation:
If a number is above 5 round up, if it is below 4 round down
Answer:
2n elements
Step-by-step explanation:
11 because 8 are in one which makes the one and then add 3 because if 3/8
The angles are B and C.
The three angles add up to 180º
A=80º
B
C
A+B+C=180º
80º+B+C=180º
B+C=180º-80º
B+C=100º (1)
The ratio between A and B is 7/13 ; therefore:
B/C=7/13 ⇒B=7C/13 (2)
With the equations (1) and (2), we make a system of equations:
B+C=100
B=7C/13
We can solve this system of equations by substitution method:
7C/13 + C=100
least common multiple=13
7C+13C=1300
20C=1300
C=1300/20
C=65
B=7C/13
B=7*65/13
B=455/13
B=35º
Answer: The measures of those two angles are 65º and 35º.
Answer:
I am think so opction (C).....
