Answer:
Step-by-step explanation :
Ratio = 3x : 4x
<h3>
Sum of angle of a quadrilateral = 360</h3><h3>
Therefore, 140+80+3x+4x = 360</h3><h3>
220+7x = 360</h3><h3>
7x = 360-220</h3><h3>
x= 140/7</h3><h3>
x=20</h3><h3>
3x= 3×20=60</h3><h3>
4x=4×20=80</h3>
Answer:
60 and 80 degrees.
Step-by-step explanation:
The other 2 angles have the sum : 360 - (140 + 80)
= 360 - 220
= 140. (because the 4 angles in a quadrilateral add up to 360).
As the other 2 angles are in the ratio 3:4 one angle = 3/7 of 140 and the other is 4/7 of 140.
This is equal to 3 *20 and 4 * 20 = 60 and 80 degrees.
