please answer this as fast as u can​

Answer 1

Answer:

1. 69*,138*,59*,94*

2. 18cm, 30cm, 18cm, 30cm

3. 80*, 140*, 80*, 60*

Explanation:

1. As the angle sum property of quadrilateral is 360*

x+2x+x-10+x×25=360

5x+15=360

5x=345

x=69

we can put the value of x and find out all the angles.

2. Let the measurement be 3x and 5x

as opposite sides of a parallelogram are equal

3x+5x+3x+5x=96(perimeter is sum of all sides)

16x=96

x=6

Again we can put the value of x and find out all sides.

3. let the angles be 3x,4x,7x and 4x

3x+4x+7x+4x=360(sum of angles of a quadrilateral)

18x=360

x=20*

We can put the value of x and find out all the angles.
