Two angles of a quadrilateral measure 210° and 20°. The other two angles are in a ratio of 6:7. What are the measures of those two angles?

The sum of first angle second angle =150

⇒  The ratio of third and fourth angle is 2:3

⇒  Let third angle fourth angle be 2x and 3x.

Step-by-step explanation:

150 +2x+3x=360

⇒  5x=210

⇒  x=42

⇒  Now, 2x=2×42

=84

⇒  3x=3×42

=126  

⇒  The measure of two angles are 84

 and 126

PLEASE GIVE BRAINLIEST

Step-by-step explanation:

Sum of angles of quadrilateral = 360 degree

so 210+20+6x+7x = 360

230+13x= 360

13x= 360-230=130

x= 130/13=10

so third angle =6x= 6*10=60 degree

and 4th angle= 7x= 7*10=70 degree

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.
