BRAINLIESTT ASAP! PLEASE HELP ME :)<br><br> Solve for x in the figure below. Show your work.
nikdorinn [45]

Answer:

x = 19°

Step-by-step explanation:

we can see from observation that 22° and (3x+11)° are complementary. I.e they add up to 90°

hence

22 + (3x+11) = 90

22 + 3x+11 = 90

33 + 3x = 90   (divide both sides by 3)

11 + x = 30  (subtract 11 from both sides)

x = 30 - 11

x = 19°

A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glide
NISA [10]

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

/24/^{2} = /x/^{2} + /13/^{2}

576 = x^{2} + 169

x^{2} = 576 - 169

   = 407

x = \sqrt{407}

  = 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

A student solved 6x+4=2(x−8) in four steps as shown:
mr_godi [17]
The first thing you should do is solve the equation yourself.

1) Distribute the 2.  
6x + 4 = 2x – 16

2) Next, you'll want to get the x's on one side. So add -2x to both sides.
6x + 4 + -2x = 2x + -2x - 16
4x + 4 = -16

3) Now subtract 4 from both sides
4x + 4 – 4 = -16 – 4
4x = -12

4) Finally, divide both sides by 4
4x/4 = -12/4
x = –3

To solve this problem all you need to do is look back out you work, and figure out the correct solution. The answer the question is The student made an error in Step 1.
