HELP Plssss..... The m
hammer [34]

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

Hope it helps....

You first need to convert the fractions so they are both eighths.

1 3/4 = 1 6/8

Then you simply need to add:
1 6/7 + 3 3/8 = 4 9/8 = 5 1/8

Your answer is 5 1/8.
