X equals 38. That means, angle R is 38, angle P is 69, and angle Q is 73.
You get x=38 by doing x+35+x+2x-7 = 180
*Hope this helps!*
Would -3,-4 be your answer to get the X intersept
Answer:
x=18.7
Step-by-step explanation:
x+17+5x+10+4x-34=180
10x-7=180
10x=187
x=18.7
all angles in a trianlge add up to 180 degrees
To find the gradient of a line you use this equation: Rise / Run
I am assuming this is a graph where both the x and y-axis increase in value by one.
So first of all, you should draw out this graph.
Second, draw a point at each of the given coordinates.
Now, join these points by drawing a right angle triangle. Put simply, draw a line from the point (4, -7) down until it is on the same level as the point (2, -3), then draw a line across.
Finally, measure the length of both these sides and use them in the equation above.
Let's assume the rise (vertical line) and the run (horizontal line) are 5 and 8 respectively. We can do 5/8 to get a gradient which is 0.625.
Step-by-step explanation:
- volume of cylinder=90π
- πr²h=90π
- 3²h=90
- 9h=90
- h=90/9
- h=10
hope it helps.
