In the unfolded COD angle, an OB beam was drawn COB = 110 Find BOD-?
| August 16, 2021 | education
Since the expanded angle is 180 °, the angles formed by the OB beam are adjacent.
The sum of adjacent angles is also 180 °
Since one of the angles is 110 °, the second can be found by subtraction.
180 – 110 = 70 ° – BOD angle.
Answer: BOD angle is 70 °
