true because integers are all positive numbers, their opposites (negatives), and zero
To find out if the triangle is a right triangle, we must check if the following equation is true:

on the left side, we have:

and on the right side, we have:

since on both sides we get 625, we have that the brace forms a right triangle.

Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) = 
6.31 = 
w = 
w = 9.82
Similarly,
tan(39°) = 
0.81 = 
0.81 = 
9.82 + x = 
x = 76.56 - 9.82
x = 66.74
The quotient if the equation is x3
