The correct answer to this question is letter "C. distance." An isometry is a transformation that preserves distance. Isometry is a geometrical transformation that preserves geometrical properties such as distance. In mathematics, an isometry (or congruence, or congruent transformation) is a distance-preserving injective map between metric spaces.
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
Y - 1 = 4y - 2/3. Move the ys over to one side, +4y crosses over to become -4y,
and -1 crosses over the right side to become +1.
y -4y = -2/3 + 1
-3y = 1 - 2/3
-3y = 1/3 Divide both sides by -3.
-3y/-3 = (1/3) / -3.
y = 1/3 * -1/3
y = - 1/9
Answer:
x = 55°
Step-by-step explanation:
x = 180° - 85° - 40° = 55°
So, 3 goes into 8 2 times and 2 will be left over so you would put:
2 2/8 or 2 1/4
