Answer:
51
Step-by-step explanation:
First you put all your numbers in order from least to greatest
Then you go from left to right crossing out the numbers
And which ever one is in the middle is the median.
14+12+x=-34 Subtract 14 from both sides
12+x=-48 Subtract 12 from both sides
x=-60
The ratio can be determined as,
Thus, the requried ratio is 7:12.
Answer: Yes, it is a right triangle
Step-by-step explanation:
Use the pythagorean theorem in order to determine whether this triangle is a right triangle. Plug in the values given in the problem (4, 7.5, and 8.5) into this equation (a^2+b^2=c^2). This gives you 4^2+7.5^2=8.5^2, and this equation is valid because 4^2+7.5^2 does equal 8.5^2.
