Question

3. Find the measure of all the four angles formed by the line segments AC and BD.
​

Answer 1

Step-by-step explanation:

$2x + x = 180(linear \: pair \: angle) \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60 \\ . ^{.}. 2x = 120 \:$

angle BOC= 2X= 120° (VERTICALLY OPPOSITE ANGLES)

ANGLE AOB= X= 60°

ANGLE AOD= 120°

ANGLE COD= X= 60°( VERTICALLY OPPOSITE ANGLES)
