Answer:
x=30 , <HFC= 120 , <DBG=60
Step-by-step explanation:
First when I take a look at these types of problems I always make sure to look around and see if there is anything that can help me.
A very key thing to remember is that all angles that are on a line will = 180
So looking at the angles and just normal geometry rules you can know that 2x+4x=180 cause the inner angles add up to 180.
So then if 6x=180 then divide by 6 to get 30 for finding x!
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5
then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
