For this case we must solve the following system of equations:
We multiply the first equation by -2:
We add the new equation with the second one:
We have different signs subtracted and the sign of the major is placed:
Now we find the value of the variable "y":
Thus, the solution of the system is given by:
Answer:
Πr^2(h)
π(1.2)^2)(4)=18.1 ft^3
22*18.1=398.2
Answer:
Angle 1 - 51
Angle 2 - 39
Angle 3 - 90
Angle 4 - 51
Angle 5 - 17
Angle 6 - 129
Step-by-step explanation:
Angle 1 = 180 - 90 - 39 = 51
Angle 2 = 90 - Angle 2 (51) = 39
Angle 3 = 90
Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51
Angle 5 = 180- 90 - 34 -39 = 17
Angle 6 = 180 - Angle 4 (51) = 129
