180-90=3x
90=3x
X=30
90+x+y=180
90+30+y=180
120+y=180
Y=60
17 18 10 that’s the answers
Answer:
She would earn $94.55
Step-by-step explanation:
Help: All triangle have angles that add up to 180, for isosceles triangles 2 of the angles are the same 1 is different. You need to know at least 1 angle. A = Angle.
A times 2 - 180 = x
Two angles are the same 1 is gotten from the equation
To find the sum of the interior angles of a hexagon, divide it up into triangles. The sum of each triangle is 180 degrees.
We get.... 4 x 180°=720°
So to sum it up....the sum of the interior angles of a hexagon is 720 degrees.
