Answer:
Step-by-step explanation:
Remark
This has nothing to do with parallel lines. All you need use is opposite angles (like k and 98 ) for example, and supplementary angles like h and 127.
h + 127
These 2 are supplementary.
h + 127 = 180 Subtract 127 from both sides.
h+127-127=180-127 Combine
h = 53
g and 127
g = 127. These two angles are opposite each other. (More correctly vertically opposite.
98 and k
These two are also vertically opposite
k = 98
m + 98 are supplementary. They add to 180 degrees.
m + 98=180 Subtract 98 from both sides of the equation
m + 98-98 = 180-98 Combine
m = 82
Answer: y=x estimate: 88

Answer: 15 students
Step-by-step explanation:
From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.
The number of students that earned straight As will be:
= 10% × 150
= 10/100 × 150
= 0.1 × 150
= 15 students
Try this solution:
Common view of the equation of the circle is (x-a)²+(y-b)²=r², where point (a;b) is centre of the circle, r - radius.
1. using the coordinates of the centre and point (2;13) it is possible to define the radius of the circle: r=√(5²+12²)=13;
the equation is (x+3)²+(y-1)²=13² or (x+3)²+(y-1)²=169;
2. using the coordinates of the centre and the radius: (x-2)²+(y-4)²=6² or (x-2)²+(y-4)²=36.
