Question

A quadrilateral has two angles that measure 190° and 20°. The other two angles are in a ratio of 2:13. What are the measures of those two angles?

Answer 1

Answer:

let the smaller of the unknown angles be 5x and the larger of the two be 16x

so 130+20+5x+16x = 360

21x = 210

x = 10

so the two missing angles are 50° and 160°

check: 50+160+130+20 = 360

50:160 = 5 : 16

Answer 2

Answer:

20and 130

Step-by-step explanation:

the measure of remaining two angles=360-(190+20) =150

2x+13x=150

x=10

therefore remaining angles are 20 and 130.
