Answer:

  • x = 88.76°

Step-by-step explanation:

<u>Use the law of cosines:</u>

  • cos C = (a² + b² - c²)/(2ab)

<u>Apply to the given triangle and solve for x:</u>

  • cos x = (52² + 48² - 70²)/(2*52*48)
  • cos x = 108/4992
  • cos x = 0.02163461538
  • x = arccos 0.02163461538
  • x = 88.76°

First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.

Hope this helps

Answer:  (- 7 )

Step-by-step explanation:

<h2>(\frac{7}{8} )(-16) (-7) (-\frac{1}{14} )</h2><h2>(\frac{7}{8} )(-\frac{16}{1})  (-\frac{7}{1} ) (-\frac{1}{14} )</h2>

simplify numerators and denominators.

∴ we get (-7)

Answer:

<DEF = 107

Step-by-step explanation:

The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.

180 - 135 = 45

After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:

180 - 28 - 45 = 107

Making the answer 107 for the measure of <DEF
