Since there are 3 sides of a triangle, and you already have two sides, just subtract the sun of the two sides from the total. You have 6 and 7 meters. Combine those into 13, then subtract if from 23. You get 10 meters. So, the mystery side would be 10m.

Alexandra [31]

Answer:

{3x}^{2}   - 4x + 10 = 0

The sum of the measures of angles xand y is 120°. The measure of the angle x is 12 less than the measure of the angle y. Find x
Troyanec [42]

Answer:
x = 54°
y = 66°

Step-by-step explanation:

x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
