Habit of mind This auto Be Easy
My math teacher, Mr. Numeric went to the auto show last week. I made the mistake of asking him what he saw. Here was his response:I’m glad you asked, I made several interesting observations. As you might have guessed, every red car was a sport car but I found it odd that half of all the blue cars were sports cars there were red. I counted 40 blue and 30 red cars. Now ,can you tel me how many sports cars were neither blue nor red?

inverse property is the answer

step-by-step explanation:

the olimpics is not going to wokk out

step-by-step explanation:

  b:   ∠x = 28.6°, ∠y = 31.2°, ∠z = 120.2°

step-by-step explanation:

this is one of those questions where "test taking skill" is all you need. the only answer that has angles that sum to 180° is the one shown above. the remaining choices do not describe the angles of a triangle.

if you want to do more work than simply adding the offered numbers, you can also check them against the law of sines. it should be true that

  x/sin(x) = y/sin(y) = z/sin(z)

and all of these ratios must be greater than 15, the longest side length.

if you want to solve the triangle from scratch, i'd suggest solving for the largest angle using the law of cosines.

  z² = x² +y² -2xy·cos(z)

  z = arccos((x² +y² -z²)/(2xy)) = arccos(-75.11/149.4) = 120.182°

now you can find y from the law of sines

  y = arcsin(y/z·sin(z)) = 31.242°
