Answer:
No
Step-by-step explanation:
By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.
Thus, where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then
which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.

Answer:
∠P = 27°, ∠Q = 39°, ∠R = 114°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°.
P +Q +R = 180°
(x +8)° +(2x +1)° +(6x)° = 180°
9x +9 = 180 . . . . . . . . divide by °, simplify
x +1 = 20 . . . . . . . . . . divide by 9
x = 19 . . . . . . . . . . . . . subtract 1
P = (x +8)° = 27°
Q = (2x +1)° = 39°
R = 6x° = 114°
Answer:
1700 meters / hour
Step-by-step explanation:
160x20 = 3200
3200/ 2 = 1700
