What is the value of the missing angle *image of a triangle and a square put together that essentially form a hexagon. the 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 any of my choices. That’s c.. I was confused lol can someone please explain The way to get the answer is simple. You have a square and a triangle glued together creating a 5 sided figure. We know that 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 is equal to the number of sides of your figure
once you know you know 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
