some one help in this question

pls i will mark as brainliest plsss

Answer 1

Answer:

Let one angle=x

Let second angle=2/3of x =2/3x

1st angle+2nd angle=180°

x+2/3x=180°

5/3x=180°

x=180°×3/5

x=36×3

x=108°

so one angle=x=108°

second angle=2/3x=2/3×108°=72°

Answer 2

Step-by-step explanation:

We know the adjacent angles of a parallelogram are supplementary.

Now one angle is 2/3 of the other. Let the smaller angle be x, which is 2/3 of the other. Let the other angle be y.

x = 2y/3

y = 3x/2

Now we now that x+y = 180, so:

x + 3x/2 = 180

5x/2 = 180

5x = 360

x = 72

Smallest angle is 72. (Bigger one is 108)
