Two lines intersect in a plane in form for angles what are the angles formed fathers intersect is a 53° angle what are the measu
DedPeter [7]

Answer:

53°, 127°, 127°

Step-by-step explanation:

<u>Two intersecting lines form two pairs of angles:</u>

  • Pair of vertical angles. They are opposite to each other and are equal
  • Pair of adjacent angles which are supplementary angles and their sum is  180°

<u>So if one of the angles is measured 53°, then the other angles are:</u>

  • 53°- vertical angle with the first one
  • 180° - 53° = 127°
  • 180° - 53° = 127°

Machine A working alone can complete a job in 3 1/2 hours. Machine B working alone can do the same job in 4 2/3 hours. How long
SIZIF [17.4K]

Answer:

B) 2 hours

Step-by-step explanation:

If machine  A complete a job in 3 1/2 hours or 7/2 of an hour

means that in one hour finished 1÷ 7/2     or  2/7

If machine  B complete a job in 4 2/3 hours or  14/3 of an hour

means that in one hour finished 1÷ 14/3    or  3/14 of an hour

Then the two machines working together in one hour will make

2/7 + 3/14    =  (4 + 3)/ 14

or   7/14   = 1/2

half of the job. Therefore these two machines working together will take two hours

Sin(13pi/2) in periodic function
Nataliya [291]
Answer: 1
13pi/2 can be simplified onto 6 pi/2, so it goes around the unit circle 6 times and left with pi/2. the coordinates of pi/2 is (0,1). the trigonometric function sin is y/r. since r is always 1 on the unit circle, the answer is the y value, in this case it is 1.
