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!
A as let’s say we have an isosceles triangle two of the sides are the same but one of the sides usually the base us different . Therefore , for this question the sides will both be equal so both 6 and the base 12-different HOPE THIS HELPS (Brainly best answer pleasee )
Given sides are 4x10x7. A rectangular prism with have 4 sides and 2 ends...we know area is length x height.. so the first side is 10x7 = 70mm. There are 4 sides so 70 x 4 = 280mm, then the end is 4x7 = 28. There are 2 ends so 28x2= 56mm. Combine 280+56 = 336mm. Hope that helps.

0,8 is the answer because 5*6+1/6=5,2 and 6-5,2=0,8
