Calculate the value of x.

~ There is a hint but. I stil don’t understand so can someone just do it for me and explain it? :3

x= 103°

Step-by-step explanation:

The angle next to angle x is 77° because it is a corresponding angle to the original 77° angle (corresponding angles is basically a pair that lies in the same position as each other, as is the case with the 77° angle and the angle to the right of x°).

Now that we know that the adjacent angle to x is 77°, you can find x. Note that the line x and 77° are lying on is parallel. This means that they are supplementary angles, which means that the sum of both angles is equal to 180°. Insert this into an equation:

Solve for x. Use inverse operations to subtract 77 from both sides:

Simplify subtraction:

x is 103°.
