Question

help The measure of angles of triangles y, (y+10)° and (Y - 40)° Find the angle measure of m of each angle​

Answer 1

Answer:

70° , 80° , 30°

Step-by-step explanation:

By using Angle sum property

y + (y+10°) + (y-40°) = 180°

3y -30 = 180°

3y = 210°

y = 210°/3

y = 70°

• y = 70°
• y + 10° = 80°
• y - 40° = 30°

Answer 2

Step-by-step explanation:

we know that sum of angles is 180

so 3y - 30 = 180

3y = 210

y = 70

so angles are 70, 80, 30
