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
Let me know if you need any further explanation.

Answer:
D) 250
Step-by-step explanation:
A) 552
552 ÷ 2 = 276
552 ÷ 5 = 110.4
B) 255
255 ÷ 2 = 127.5
255 ÷ 5 = 51
C) 525
525 ÷ 2 = 262.5
525 ÷ 5 = 105
D) 250
250 ÷ 2 = 125
250 ÷ 5 = 50
D is the only answer where both 2 and 5 divide evenly, so it is your answer.
Hope this helps :)
Answer:
-4
Step-by-step explanation:
First you wanna subtract the 1 from the 11 then add subtract the 3x from the 6x and you should have 3x = -12 the. You just divide -12 by 3
