I need help getting the answer. Getting the answe for “x”

80 degrees

Step-by-step explanation:

Inside the angles will add up to 180 degrees.

Therefore we need to add 130+105+45 = 280

Next, take 360-280= 80 degrees

- If you would like to check, look at the angle within the shape. Since it is a little less than a right angle (90 degrees) we know that 80 degrees is the correct answer.

- Hope that helped! Let me know if you need further explanation.

answer: okw

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
