Where is the persons info

The value of
.


We know that,

➪ 125° +
+ 30° = 180°
➪
+ 155° = 180°
➪
= 180° - 155°
➪
= 25°
Therefore, the value of
is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.

✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.


Gradient of line,m=(17-6)/(20-0)=11/20
finding equation of line using a point (20,17)
y-17=11/20(x-20)
y-17=(11/20x)-11
y=11/20x+(17-11)
y=(11/20)*x+6
To find the volume of a cone, you use the formula

.
Radius squared would be 36 in our case and 36 times 3.14 is 113.04. 6 thirds is also two, so multiply that by two and you would get 113.04 x 2 = 226.08. So, your answer would be 226.08 cubic meters of dirt.
Answer:
-1
Step-by-step explanation:
The slope of the line can be found by
m = (y2-y1)/(x2-x1)
= (-2-1)/(1--2)
=-3 /(1+2)
=-3/3
-1
