Answer:

∡3=142°

Step-by-step explanation:

∠3 and 38° are supplementary angles, which means their sum must equal 180°, therefore, we make an equation and solve for ∡3:

∠3+38°=180°

∡3=142°

So ∡3=142°

Please answer all the questions shown in the image below

kompoz [17]

Answer:

A-

first x=1 and y=5

then x=2 and y=10

then x=3 and y=15

then x=4 and y=20

YES they are proportional because the answer every time is 5x

B- The x coordinate is growing by one and the y coordinate is growing by 5

C- for 0 t-shirts the y coordinate would be 0 as well, and for 5 shirts it would be 25 (5*5)

Focus on Math-

no it would not because instead of the equation looking like 5x it would look like 5x+4

Enjoy!!
