Answer:

The four angles are 82 degrees, 98 degrees, 82 degrees and 98 degrees.      

Step-by-step explanation:

We are given the following in the question:

Measure of two adjacent angles are:

\angle 1 = x + 34\\\angle 2 = 2x + 2

Since the two angles are adjacent, the sum of the angles will be 180 degrees as they form a straight angle.

Thus, we can write:

(x + 34) + (2x + 2) = 180\\3x + 36 = 180\\3x = 180-36\\3x = 144\\x = 48

Thus, the angles are

\angle 1 = \angle 3 = 48 + 34 = 82^\circ\\\angle 2 = \angle 2 = 2(48) + 2 = 98^\circ\\

Thus, the four angles are 82 degrees, 98 degrees, 82 degrees and 98 degrees.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em>Approximate the value of </em>\sqrt{11}<em> to the nearest tenths place. Plot the approximation on the number line.</em>

(Please have a look at the attached photo)

My answer:

The value nearest tenths place of \sqrt{11} is: 3.3

Hope it will find you well.

How far is the portion of her route from A to D? Round to the nearest whole number. Explain. I NEED IT BY TONIGHT SO PLSS SOMEON
inn [45]

9514 1404 393

Answer:

  A to D is about 2087 ft

Step-by-step explanation:

For the portion of the path of interest, the sine and cosine relations apply.

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

__

AB is the adjacent side to the angle marked 33°, with hypotenuse 975 ft.

  cos(33°) = AB/(975 ft)

  AB = (975 ft)cos(33°) ≈ 817.70 ft

BC is the opposite side in the same triangle.

  sin(33°) = BC/(975 ft)

  BC = (975 ft)sin(33°) ≈ 531.02 ft

CD is the hypotenuse of the right triangle BCD. The side BC that we know is opposite the given angle, so the sine relation applies.

  sin(46°) = BC/CD

  CD = BC/sin(46°)

  CD = (531.02 ft)/sin(46°) ≈ 738.21 ft

__

Now we know the segments of the path of interest:

  A–D = AB +BC +CD

  A–D = 817.70 ft + 531.02 ft + 738.21 ft = 2086.93 ft

  A–D ≈ 2087 ft

_____

<em>Additional comments</em>

The attachment shows all of the segments computed working counterclockwise from A. The angles in triangle DEF are computed using the Law of Sines from sides DF and DE and angle DEF. Segments EG and GH are computed using the Law of Cosines.

When we get to points F, G, H, we find that there is some inconsistency with the locations that would be computed working clockwise using AB and angle BFA. This inconsistency shows up in an error in the 119° angle in the attached figure.

This means that segments on the back side of the route, along path EFGHA, will vary somewhat depending on how they're computed.

We assume that points B, C, F, G are collinear.
