Imagine

at the top of the triangle and

at the bottom. (or used the attached picture for reference)


One thing to note, however, is that the side opposite

is the same side as the one adjacent to

! Thus

.
Substitute these values for

and

and solve.
The second one is but i’m so so sure
Answer:
See below ~
Step-by-step explanation:
Anthony has graphed the inequality y ≤ -2x + 1.
For an inequality using a > or < sign, a <u>dotted line</u> has to be used instead of a solid line.
Answer:
The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Step-by-step explanation:
A line is a polynomial function of the first degree that has the following form:
y = m * x + b
where m is the slope of the line and b is the intercept with the Y axis. The slope is the inclination of the line with respect to the abscissa axis.
In this case you know that the slope of line a is ½.
Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.
You have:
- y+½x=2 → y= -½x +2
- -2x+y+2=0 → y=2x -2
- 2x-2=y
The line that has the same slope as line a is the last one, so <u><em>the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0</em></u>
