An exterior angle of a triangle is equal to the sum of the opposite interior
angles
4x - 20 = 2x - 4 + 52
4x - 2x = 20 - 4 + 52
2x = 68
x = 68/2
x = 34

Answer:
825
Step-by-step explanation:
Let the number of students who participated in the sport be x, which is equivalent to 0.825
The total number of students in the school is equivalent to 1
Expressing mathematically,we obtain
0.825:x=1:1000

By cross multiplying we obtain,

We finally simplify to arrive at

Hence the number of students who participated in the sport is 825
Answer:
(-1,-1)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(1+-3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(-6+4)/2 = -2/2 = -1
(-1,-1)
