Answer:

30° , 170°

Step-by-step explanation:

Let the remaining two angles be 3x & 17x. As it is a quadrilateral , the sum of all the angles of quadrilateral is 360°. So,

[tex]3x + 17x + 60 + 100 = 360[/tex]

[tex] = > 20x + 160 = 360[/tex]

[tex] = > 20x = 360 - 160 = 200[/tex]

[tex] = > x = \frac{200}{20} = 10[/tex]

Putting the value of x , remaining angles are

(3×10 = 30°) & (17×10 = 170°)

Answer:

30° and 170°

Step-by-step explanation:

the missing angles 3:17

3x+17x+60+100=360°

20x+160=360°

20x=360-160

20x=200°

divide both sides by 20

X=10

substitute X=10 in 3x and 17x

3(10)=30°

17(10)=170°
