The measure of angle F is 130 degrees.A part of angle F measures 70 degrees. What is the measure of the other part if the angle?
Answers
130 degrees is the total degrees of the angle, So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle. (130-70=60) The missing angle equals 60 degrees
i think its 60 because 130-70 = 60
A triangle has an angle that measures 80°. The other two angles are in a ratio of 7:13. What are the measures of those two angles?
Answers
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.

The male to female ratio in Taiwan is 52 to 48.Write this ratio as a fraction in reduced form. Please show work. Thanks
Answers
52/48 reduce since they are both even start with 2 52/48= 26/24 divide by 2 again 13/12 cannot be reduced any more since 13 is a prime number 13 males/12 females
hope this helps
52=2*2*13 48=2*2*2*2*3 cancle the factors which are common
