45x+angle trs = 180   straight line


angle trs = 180-45x


angle trs + angle t + angle tsr = 180  (sum of angles in a triangle =180)


(180-45x) + 25x + 57+x = 180


combine like terms


180 +57 -45x+25x+x=180


237-19x=180


subtract 237 from each side


-19x =-57


divide by -19


x=3

Find the area of the triangle with vertices: q(3,-4,-5), r(4,-1,-4), s(3,-5,-6).
maw [93]

Answer:

  (√6)/2 square units

Step-by-step explanation:

The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.

  QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)

  QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)

The cross product is the determinant ...

\text{det}\left|\begin{array}{ccc}i&j&k\\1&3&1\\0&-1&-1\end{array}\right|=-2i+j-k

The magnitude of this is ...

  |QR × QS| = √((-2)² +1² +(-1)²) = √6

The area of the triangle is half this value:

  Area = (1/2)√6 . . . . square units

A recipe for apple pie calls for 1.2 kilograms of apples. If the average apple has a mass of 200 grams, how many apples should b
lutik1710 [3]

Answer:

6Apples

Step-by-step explanation:

Number of apples required for the recipe  = 1.2kilograms

But we know that 1000g  = 1kg

So;

       1.2 kg will give:

             1.2  x 1000 = 1200kg

Average mass of the apple  = 200g

So;

  The number of apples used  = \frac{1200}{200}  = 6Apples
