Question

Please help i need to redo​

Answer 1

Answer:

Step-by-step explanation:

4x+4+2x+2+7x-8=180

add like terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

add ur stuff up see if u get 180

60+30+90=180

Answer 2

#1:

A)

you need to know where a vertex goes on a isosceles triangle...

I attached a picture that explains it.....

you also want to label triangle.... XYZ

I put a picture on of how you should of labeled the triangle...

B)

so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.

so your equations will need to be equal to 180.

4x+4+2x+2+7x-8=180

so we combine liked terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

now you want to check you answers so add them up to see if your answers equal 180...

60+30+90=180

to be continued.... i do second question on a second answer since i dont want pictures to get mixed up
