The sum of measures of angles A and B is 90°
Hence the angles are complementary
- As complementary angles have sum 90°
For number 3 add all the numbers and divide how numbers you have
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (-3, 1) and (2, -4). Substitute:
Therefore we have the equation of a line
Put the coordinates of the point (-3, 1) to the equation:
<em>subtract 3 from both sides</em>
<h3>Answer: y = -x - 2</h3>
Answer: d is correct
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Yes they are because if you divide 18 by 3 you get six and if you divide 15 by 3 you get 5, so it simplifies to 6:3 which is the same as the ratio for rings
