I need help please with the work?

Answer:

A.) 48°

Step-by-step explanation:

There is a right angle and an angle of 42°

Therefore

x=180-90-42. (sum of int angles of triangle)

x=48°

Answer:

(A) 48

Step-by-step explanation:

Triangles have 180°, so all you have to do is subtract the numbers you already know from 180.

180-42 = 138

The square on the left corner means that degree is a right angle. Right angles are always 90°.

138-90 = 48degrees

If I helped at all please give brainliest! :)

Final answer:

Without more context or details, we cannot determine any definitive relationships between AE and BF or AB and CD when DFB and CEA are not 90°. Generally, these lines or line segments could be skew, meaning they do not intersect and are not parallel.

Explanation:

Without additional context, specifics about the diagram, or an understanding of how AE, BF, AB, and CD are oriented towards each other, we can't determine any definitive relationships between AE and BF, or AB and CD when angles DFB and CEA don't equal 90°. However, in terms of general geometry, if you have two lines or line segments, and you know that the angles forming by intersecting lines are not 90°, then those two lines or segments are not perpendicular. In most cases, without knowing that they are parallel, AE and BF can be stated as skew lines. Similarly, unless specified, AB and CD could also be skew, not having any particular relationship. The term 'skew' is used to describe lines that do not intersect and are not parallel.

Answer:

if angle dfb and angle cea measure something other than 90degrees, then line we is not equal to line bf. in this case, line and and line cd intersect at a single point.

Answer:

x = -26

Step-by-step explanation:

x/2 + 5 = -8

First let's combine like terms.

Subtract 5 from both sides.

x/2 = -13

Multiply both sides by 2 to isolate x.

x = -26

Plug this back into the original equation to check your answer.

-26/2 + 5 = -8

-13 + 5 = -8

-8 = -8

Your answer is correct.

Hope this helps!

Answer:

x=-26

Step-by-step explanation:

x/2 + 5 = -8

x/2 + 5 - 5 = -8 - 5

x/2 = -13

x = -26

this is all of the work I did to solve what x is! I hope it helped! There are many other way to solve this problem. This is the way which a lot of ppl do.
