Answer:
Step-by-step explanation: 7
Subtract 5 on both sides to get 4x = x + 21
then, subtract x from 4x and x is 1, so 3x = 21 then divide by 3 on both sides
The main piece of computer software on which every other piece of software relies is referred to as the "operating system". It is responsible for all the major channels of communication between the software and the hardware.
This relationship again shows that since w and y are perpendicular to each other that the smaller angles will add up to give 90 degrees.
3x + 3 + 15 = 90
3x + 18 = 90
3x = 90 - 18
3x = 72
X =72/3
X = 36 degrees
Answer:
its 40
Step-by-step explanation:
