<em>x</em> and <em>w</em> are parallel lines, so
• angles 2 and the one labeled 75º are congruent because they are alternating interior angles, and
• angles 1 and 2 are supplementary because they form a linear pair.
The first observation tells you that angle 2 has measure 75º, and angle 1 has measure <em>m</em> such that
<em>m</em> + 75º = 180º
so angle 1 has measure 180º - 75º = 105º.
First we find the unit rate which would be how many words in 1 minute...
294/7 = 294 ÷ = 42 wpm
Now we multiply by how many minutes to find the total...
42 wpm × 11 min = 462 words.
