Answer:
10° and 25°
Step-by-step explanation:
The ratio of the 2 angles = 2 : 5 = 2x : 5x ( x is a multiplier )
The sum of the 4 interior angles of a quadrilateral = 360°
sum the 4 angles and equate to 360
245 + 80 + 2x + 5x = 360
325 + 7x = 360 ( subtract 325 from both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Thus
2x = 2 × 5 = 10
5x = 5 × 5 = 25
Then the 2 angles measure 10° and 25°
