Answer:

measure of angle ABC is 6 degree.

Step-by-step explanation:

After you found x, you'll plug it in the equation of the angle it's asking for.

Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

Measure of angle CBD = 2x+1.

2(1) +1 = 3

Measure of angle ABC is ABD + CBD

3 + 3 = 6

Answer:

6°

Step-by-step explanation:

We know that is 4x - 1 + 2x + 1

So it equals

6x

or 6 ( 1) = 6°

A few times, his toss was off and the paper landed on the wet grass. He know he should probably return to the house and place the paper on the driveway, but his arm usually was accurate. He figured he could always pretend he did not notice especially if no one complained. Bobby really did not like the job, but he forced himself to do it every morning.
