Lmk this answer ASAP please

angles on a line add up to 180 degrees

180 - 40 = 140

180 degrees in a triangle. going to work out the base angles for the isosceles triangle as its top angle is 140 degrees.

180 - 140 = 40

base angles are equal so 40/2 = 20 degrees

X = 20 degrees

90 degrees angle has been indicated.

90-20 = 70

180 - 70 - 40 = 70

y = 70 degrees

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
