Answer:
144&36
126&54
21&159
Step-by-step explanation:
Supplementary means angles that add up to 180 degrees
Since these angles add up to 180 degrees, they are therefore supplementary

X-10 + 2x + 1= 90°
you combine like terms:
x+2x= 3x and -10 + 1 = -9
So,
3x - 9 = 90
+9 +9
3x=99
Divide by 3,
x= 33
First Angle: x-10 (plug in 33 for x)
33-10 = 23°
Second Angle: 2x + 1 (plug in 33 for x)
2(33)+1
66+1= 67°
To Check if it’s correct and make a 90° angle:
Add 67° plus 23° which equals 90°
First angle: 23°
Second angle: 67°
Hope that help!!
Answer:
After 15 minutes, the temperature of both the furnaces will be same.
Step-by-step explanation:
Let 
be the minutes when the temperature of both becomes same.
Now, as per question:
Temperature of the furnace after minutes that is cooling at the rate of 15 degree per minute is given as:
Temperature of the furnace after minutes that is heating at the rate of 5 degree per minute is given as:
Now, equating both the temperatures, we get
Therefore, after 15 minutes, the temperature of both the furnaces will be same.
