Solve for the missing angle measurement

The total sum of angles in a trapezium is 360°.

x + 80° + 75° + 105° = 360°

x + 260° = 360°

x = 360° - 260°

x = 100°

The missing angle measurement is 100°.

Hope it helps!

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

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
