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:
t=1
Step-by-step explanation:
Answer:
D) (4,5)
Step-by-step explanation:
the ordered pair (4, 5) is the only one that, when substituted into each inequality statement, made both of them true
Equal because these numbers are of the same value
The answer would be 16.
you have to multiply 4 and 8 which =32 and then divide 32 by 2 which =16
