Since <A = <D and <B = <E, it must be true that the third angles <C = <F (the triangles are similar).
If <C = x and <F = 2x-30 then you need to find x for which <C = <F is true:
x = 2x-30
and that holds for x=30
So m<C=30 degrees

Answer:
x=-7.3
Step-by-step explanation:
x-5.1=-12.4
x=-12.4+5.1
x=-7.3
- Answer:
- (x,y)=(3/31, 107/62)
Step-by-step explanation:
{2x+8y=14
{216x-4y=14
{x+4y=7
{216x-4y=14
217x=21
x=3/31
2*3/31+8y=14
y=107/62
(x,y)=(3/31, 107/62)
2*3/31+8*107/62=216*3/31-4*107/62=14
14=14=14 since all of the equalities are true the order pair is the solution of the system (x,y)=(3/31, 107/62)
hope this helps :)
