Answer:
x=3
Step-by-step explanation:
We have to use the fact that all angles of a triangle add up to 180 and two supplementary angles add up to 180.
First,QRS forms a line, so angle QRT and angle TRS add up to 180 or, if we call angle TRS y for the sake of having it as a variable, 45x+y=180 or y=180-45x
Now we have all three angles of the triangle, and we know all three add up to 180, so startign with our newly found angle, (180-45x)+(25x)+(57+x)=180
180-45x+25x+57+x=180
237 - 19x = 180
57 = 19x
x=3

Answer:
x=-1 y=4 (-1,4)
Step-by-step explanation:
The painter needs at least two gallons of paint to cover the wall.
To get this answer, you first need to find the area of the wall; by multiplying 20.5 x 16.4. This will get you 336.2.
Then, you need to divide 336.2 by 200. This will get you approx. 1.6.
If it's asking for partial gallons as well, stop here. Your answer is 1.6.
If not, continue.
Unless you're including partial gallons, you can't get 1.6 gallons of paint, so you need to round up. This will be 2 gallons.
