Find c to two decimal places and find the measure of angle B. Angle A = 58°, Side AC = 5, Side BC = 8, Find side C. Angle C is 9
KATRIN_1 [288]

Answer:

  • c = 9.43
  • m∠B = 32°

Step-by-step explanation:

Side c = AB can be found using the Pythagorean theorem:

  c² = a² + b² = 8² +5² = 89

  c = √89 ≈ 9.43

__

Angle B is the complement of angle A, so is ...

  B = 90° -A = 90° -58° = 32°

c is approximately 9.43; the measure of angle B is 32°.

some say that to brew an excellent cup of coffee, you must have a brewing temperature off 200 degrees, plus or minus five degree
ASHA 777 [7]
Your equation for the maximum brewing temperature should be x = 200 + 5 because according to your word problem, the temp. can be five degrees above 200 degrees. 

x = 200 + 5 
x = 205

Your equation for the minimum brewing temperature should be x = 200 - 5 because according to your word problem, the temp. can be five degrees below 200 degrees.

x = 200 - 5
x = 195
