Question

What's the value of the missing angle *picture of a triangle and square put together which basically makes a hexagon.
angles are 90 degrees, 90 degrees, 130 degrees, 130 degrees. I have to find the last angle.*
A. 50 degrees
B. 60 degrees
C. 100 degrees
D. 240 degrees

I don't see the answer in one of my choices.. Please help
oops i meant its a triangle and pentagon put together
never mind I got the answer. It's c.. I was confusing myself lol
can someone explain please
The way to get the answer is simple. You have a square and a triangle stuck together creating a 5 sided figure. We know the sum of the angles of a 5-sided figure is 540 degrees from the following formula...
(n-2)*180=
(5-2)*180=
3*180 = 540 n equals the number of sides in your figure
once you know that you know that you are already given the angles of 90, 90, 130, and 130 degrees so...
x+90+90+130+130=540
x+440=540
x+440-440=540-440
x=100 degrees
