1. C is the right angle so AB is the hypotenuse and AD is the altitude to the hypotenuse.
The hypotenuse is
The area calculations must match. Let h=CD
Answer: 12
2. This is the same triangle as above. We seek x=AD and DB=25-x
AD=9 and DB=25-9=16
Answer: AD=9, DB=16
Answer:
61
Step-by-step explanation:
Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.
Simplifying, we get;
9x - 31 + 7x - 2 + 4x + 33 = 180
20x = 180
x = 9.
So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61
8 x 3 is 24
3 x 8 is 24
6 x 4 is 24
24 x 1 = 24
Hope that helped you and I didn't know when you meaned by 2 facts and 1 fact
Answer:
-3x + 31
Step-by-step explanation:
First distribute
2x + 16 -5x +15
Collect like terms
-3x + 31
Lines that are parallel have the same slope, and the given line (y = 6x - 5) has a slope of 6; we are looking for a line with a slope of 6.
To form an equation for a line, you need to know the y-intercept (the point at which the line intersects the y-axis). The first step to finding the y-intercept is to plot the given point. After you've done that, count six units up (this is our slope) and one to the right; plot the point. Lastly, draw the line by connecting the points and see where the line intersects the y-axis.
My graph shows that the line intersects the y-axis at -17. All that's left now is to put our information together into an equation. I'm assuming the problem wants the equation in slope-intercept form; slope-intercept form is y = mx + b where m is the slope and b is the y-intercept, so it would look like this:
y = 6x -17
Hope this helps.
