Help plssss I’m actually so confused
Degger [83]

Answer:

A) 2p

(because DC is twice the size of AB. Hence why they're in the ratio of 2:1)

B) p+q

(Start from B, go backs against the arrow to the left and get - p, then + q and + 2p. Simplify -p+q+2p)

Hope this helps!

Tom [10]

Answer:

see explanation

Step-by-step explanation:

Since a hexagon has 6 interior angles and the measure of one is 120°, then

sum of interior angles = 6 × 120° = 720°

exterior angle = 180° - interior angle = 180° - 120° = 60°
