Question

Plss someone help and explain if you can Plss help

Answer 1

Explanation:

44) I’ll try to explained detailed as possible.

So first of all we have: 180-120=60 => this is the value of angle(BCA)

=> we know that a triangle has 180 degree in total =>

Now we will have to add all angles,their sum will be equal to 180.

=> (2x+28)+(3x-13)+60=180

2x+28+3x-13=180-60

5x+15=120

5x=105

x=105/5

x=21

=> m(BAC) = 2x+28=29*2+28=58+28=86 degree.

Answer 2

above is the answer. typing is not getting allowed dunno why
