Find the missing angle measure in each triangle. show your work.

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for third angle

∠C = 180° - (50 + 75)° = 180° - 125° = 55°

∠B = 180° - (60 + 30)° = 180° - 90° = 90°

∠A = 180° - (45 + 30)° = 180° - 75° = 105°

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
