Answer:
8x2=16 9x7=63
63+16=79
Step-by-step explanation:
Answer: b=13.75
Step-by-step explanation:
Use Pythagorean theorem
a^2+b^2=c^2
We know c, the hypotenuse, because the hypotenuse is opposite the right angle. It is 17
We also know a, one of the legs. It is 10.
Plug the number we know into the formula
10^2+b^2=17^2
100+b*2=289
Subtract the 100 on both sides
b^2=189
Take the square root of both sides
b=13.7477271
Rounded to the nearest Hundredth,
b=13.75
Hope this helped! :)
It would be 3y.3y is ur answer
the sum of the lengths of any two sides of a triangle is always greater than the length of the third side
T=the third side
12+18>T
12+T>18
18+T>12
the first equation says that T<30
the second equation says that T>6
putting these together...
6<T<30
