Atriangle has angles with the following measures: (x2 + 34)°, (6x + 4)°, and (10x + 10)°. solve for x.

The angles in a triangle add up to 180 so:

X^2 + 34 + 6x + 4 + 10x + 10 = 180

Tidy up to get a trinomial:

X^2 + 16x - 132 = 0

Solve for x.

(X + 22) (X - 6) = 0
X = -22 or X = 6

Since an angle cannot be negative, it must be X = 6.

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
