Answer:
mABC=130°
mEBD=130°
mABE=50°
Step-by-step explanation:
Find a common denominator first
2 24/40 - 1 15/40 = 1 9/40
it is already in simplest form so you can not reduce it
Answer:
T>28
Step-by-step explanation:
Multiply 4 to both sides to get your variable alone.
It will be easier to explain how to solve this question in a square. If you rotate 4-sided square from the centre, you need to rotate it 90 degrees. The formula for this would be: 360 ° /the side count. In a square, it would be 360° /4= 90°.
In 18-sided polygon, the calculation would be: 360°/ 18 side= 20°
