Answer:
x = 45
Step-by-step explanation:
The angles labeled with the pink x are the same. Line V and Line X are parallel and alternate interior angles are equal when the lines are parallel.
We know the 3 angles inside the triangle and the sum of the angles of a triangle are 180
x+x+ 2x = 180
4x= 180
4x/4 = 180/4
x = 45
To set up the integral in sphericals, just draw a picture. The limit in θ is determined by
<span>cosθ=R−h/R</span>
Therefore, the volume of the cap is the integral
2π∫↓0↑arccos[(R-h)/R] dθ sinθ ∫↓(R-h) /cos<span>θ </span>↑R dr r²
Answer:
y= -5
Step-by-step explanation:
Answer:
the other two angles are 70° and 20°
Step-by-step explanation:
Answer:
2 1/18
Step-by-step explanation:
ok substitute w with 1/9
so the equation is now
1/2*1/9+2
Do multiplication first so,
1/2*1/9= 1/18
Now the equation should be
1/18+2
Finish it off by adding
1/18+2= 2 1/18
