<span>Opposite angles of a parallelogram are equal, so:
5x - 28 = 3x - 10
2x = 18
x = 9
Plug x = 9 into the equations
m angle 2 = 5x - 28 = 5 * 9 - 28 = 17
m angle 4 = 3x - 10 = 3 * 9 - 10 = 17
The sum of all angles in a parallelogram is 360,
and we know: m angle 1 = m angle 3, so:
m angle 1 + m angle 2 + m angle 3 + m angle 4 = 360
m angle 3 + 17 + m angle 3 + 17 = 360
2 * (m angle 3) = 360 - 17 - 17 = 326
m angle 3 = 163</span>
Answer:6
Step-by-step explanation:
You will divide 120/20
Nine groups of 8 students and one group of 6 students. 9 x 8 = 72. 78 - 72 = 6.
Answer:
The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
Step-by-step explanation:
Let the area of Country B be x
We are given that Country A is larger by 473 square kilometers.
Area of Country A = x+473
Total area of both countries = x+x+473
Total area of both countries = 2x+473
We are given that The combined land area of the countries A and B is 159,973 square kilometers.
So, 


x=79750
Area of Country A = x+473=79750+473=80223 sq.km.
Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
It would be 33.33 because you have no change 50 into a fraction and divide that by 2/3
