Answer:
the correct choice is marked
Step-by-step explanation:
The line has a rise of 2 for a run of 1, so a slope of 2. The line crosses the y-axis at y=-2, so the y-intercept is -2. The slope-intercept equation for the line is ...
y = mx + b . . . . . . for slope m and y-intercept b
y = 2x -2
Area of a triangle is,
Substitute the numbers,
The above number is the base.
Using the pythagorean method let's calculate for "c" the hypotenuse.
Substitute
Solve,
Simplify,
Calculate one last time,

Answer:
Step-by-step explanation:
The Given two angles are supplementary angles.
<u>Given angle :</u>
<u>Solution :</u>
<u>We know that,</u>
Two angles are known as supplementary angles if their sum is 180.Each angle is a supplement of other.
Let the measure of supplement be <em>y</em>.
So,
Now find the value of y of this equation, that would be the supplement.
- <em>Simplify this : </em>
Hence, 94° is the supplement of 86°.
