Answer:
0.8 < x < 16.8
Step-by-step explanation:
The third side of the triangle is always less than the other two sides combined. I think of it like if it was greater than the other two sides added, there would be no triangle- it'd be a line.
The other rule is that it has to be greater than the difference between the two lines.
I hope this helped!
Answer:
28
Step-by-step explanation:
The answer is 28 because this triangle will add up to 180 degrees and 79 + 73 = 152 and
180 - 152 = 28 so 28 is our missing angle!
Hope this helps you!
Answer:
-15 Is the answer
Step-by-step explanation:
(-5)(7)+4×5
= -15
(-5)(7) + 4×5 = -15/1 = -15
Multiple: -5 * 7 = -35
Multiple: 4 * 5 = 20
Add: the result of step No. 1 + the result of step No. 2 = -35 + 20 = -15
Hope this helps.
21,000-600 = 20,400
20,400/3400 = 6
t = 6
21,000=3,400(6)+600
21,000=20,400+600
21,000=21,000
