Two angles of a quadrilateral measure 25° and 280°. The other two angles are in a ratio of 5:6. What are the measures of those two angles?

25 and 30

Step-by-step explanation:

because one angle measures 280 and the other 25 you add it.

280 + 25 = 305

Since there is 360 degrees in a quadrilateral you subtract

360 - 305 = 55

the other 2 measures are in the ratio of 5:6

So add those to ratios 5 + 6 = 11

55/11 = 5

multiply it by the ratio

5 * 5 = 25

5 * 6 = 30
