Plz help on these two.

5)x= 67° and y= 32°

(x-15)°=52°(vertically opposite angles)

=>x= 52+15° = 67°

Similarly, 4y= 128°(vertically opposite angles)

=>y=128/4= 32°

6) x= 5° , y= 22°

12x+15=75°(vertically opposite angles)

12x=75-15°

12x=60°

x= 5°

6y-27°=105°

6y= 105+27°

6y= 132°

y= 22°

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
