4x-55 would be what’s ced
Bec 4x-5
Lyrx [107]3 years ago

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees

Hey loves!!! Can any of you lovely people give me a hand?
posledela

Hey There!!

Your best answer will be A.

Step-by-step explanation:

Because, The SAS stands for Side Angle Side if you need two sides and then the angle needs to be between them.

The first one works because the angle is in-between the 2 sides. The second one really doesn't work very well. Because, It actually have 2 angles and it only need one. Well, The third one it doesn't work because the angle isn't between from both sides. The fourth one doesn't work at all they are only sides and no angles. Hope This helps <3!!
