Answer:
The answer is B
Step-by-step explanation:
They both equal one 180 so add like terms and solve
100 by 65 = 330 perimeter = 6,500 area
90 by 75 = 330 perimeter = 6,750 area
<BAC = <DEC = 30°
<BCA = <DCE = 70°
<CDE (or m<D) = 180° - <DEC - <DCE
<CDE = 180° - 30° - 70°
<CDE = 80°
The number that belongs in the green box is 80
Answer:
720º
Step-by-step explanation:
We can use vertical angles to figure this out. We can see that each of the unmarked angles in the triangles is a vertical angle to an empty space. A full circle has the measure of 360º. We need half of that which is 180º.
The sum of the angle measures of a triangle is 180º. We have five triangles so the total angle meaure is 900º.
However, we need to subtract the 180º to get 720º.
Answer:
12
