Need answer ASAP! Please see screen shot.
vivado [14]

Answer:

0.4 or \frac{2}{5}

Step-by-step explanation:

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator (\frac{x}{30}). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator (\frac{12}{y}). Plug in the entire fraction and you get \frac{12}{30}. Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get \frac{2}{5}. Either one works, depending on what your question asks for.

Answer:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Step-by-step explanation:
