The three angles create a triangle. The sum of the angles of a triangle is always 180°.
Solving for x,
45° + 35° + x = 180°
x = 100°
Answer:
- The height of the other book is <em>2 3/4</em> inches.
Step-by-step explanation:
<em>From the information,we get:</em>
Two stacks of books together are = 7 1/2 inches tall.
One stack is given,that is = 4 3/4 inches.
To Find:
Solution:
Let us assume that the other height of the book be x.
Then the equation will be:
- Solve for x to get the other book's height.
Convert the mixed fractions to fractions:
<em>Subtract 19/4 from both sides:</em>
<u>Hence, we can conclude that:</u>
The height of the other book is 2 3/4 inches.
The answer should be 0. 38
Answer:
y = 2/5x -2
Step-by-step explanation:
First, establish two points. I'll use the intercepts for this problem.
(5, 0), (0, -2)
To find slope, divide change in y by change in x.
Change in y --> 0 - (-2) = 2
Change in x --> 5 - 0 = 5
<em>Slope = 2/5</em>
<u>Next, find intercept.</u>
Plug in slope for one of the points and find how you can make that equal to the y coordinate by adding/subtracting
0 · 2/5 + ? = -2
? = -2
<em>y intercept = -2</em>
Or if the line intercepts the y-axis at a definite point like this graph, just find where it intercepts.
<u>Putting it Together</u>
Now just put this into slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept.
<em>y = 2/5x - 2</em>
