Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Answer:
Step-by-step explanation:
-Given the cone's height is 9.1m and the Circumference is 12.1
#We use the circumference formula to calculate the radius:
-The volume of the cone using the radius above can then be calculated as follows:
Hence, the cone's volume is 
Answer:
3x-y=2
Step-by-step explanation:
y=3x-2 minus 3x
-3x+y=-2 divide by -1
3x-y=2 answer
