ELEN [110]4 years ago

Answer:

<h2>Complementary angles.</h2>

Step-by-step explanation:

The graph is attached.

Notice that \angle a=\angle AXY, \angle b = \angle YXB and \angle BXC = 90\°, by given.

\angle AXB = \angle AXY + \angle YXB, by sum of angles.

\angle AXB + \angle BXC = 180\°, by supplementary angles definition.

\angle AXB + 90\° = 180\°\\\angle AXB = 180\° - 90\°\\\angle AXB = 90\°

Which means,

\angle AXB = \angle AXY + \angle YXB = 90\°

Therefore, \angle a + \angle b = 90\°, in other words, angles a and b are complementary by defintion.

So, the right answer is the second choice.

What is an equation of the line that is perpendicular to y-4=2(x-6) and passes through the point (-3,-5)
krok68 [10]

Answer:

y+5 = -1/2(x + 3)

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. The slope of the line

y - 4 = 2(x - 6) is 2. Its negative reciprocal slope is -1/2.

Using m = -1/2 and the point (-3,-5) in the point slope form.

y --5 = -1/2(x--3)

y+5 = -1/2(x + 3)

Find the value of W and X
notka56 [123]

Answer:

W = 13.33

X = 13.10

Step-by-step explanation:

You use Trig

S = O/H. C = A/H. T = O/A

For W we have to find Adjacent using Opposite, so we're going to use Tangent

Now we have Tan = O/A and rearrange this to find Adjacent

Tan = O/A --> ATan = O --> A = O/Tan

then we plug in A = 12/Tan(42°) which gives us 13.3273.... I usually round up to the 2nd decimal, so 13.33

To find X we do the same thing with a little bit of additional work

Since we already did the work for the last one, we can just skip a few of those steps

A = 12/Tan(27°) which gives us 26.4322..... or 26.43

But that gives us the whole bottom bit, which is X+W, so just subtract the W

26.43 - 13.33 = 13.10

Sorry if I'm bad at simplifying my wording

I hope this is correct, my math seems right, but the picture is not to scale

Step-by-step explanation:

1/6 page is multiplied by 6 to get 1 whole page, so you have to multiply the time 1/12 of a minute by 6 to get 1/2 minute.
