Answer:
Step-by-step 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.
