Answer:
The temperature changed by 45˚
Step-by-step explanation:
Set up an algebraic equation
-5 + x = 40
Add 5 to both sides
x = 45
3x + 4y is simplified
x = 5
Add three to 17 and your answer will be 20, then divide 20 and 4 and your answer is 5
the distance is 8
40 degrees is acute, 50 is also acute and they both make up a right angle (90 degrees)
