Answer:

A=20 degrees

Step-by-step explanation:

All of the interior angles of a triangle must add up to 180 degrees, so:

2x+5x+11x=180

18x=180

x=10

A=2(10)=20

Hope this helps!

Answer:

Angle A = 20 degrees

Step-by-step explanation:

The sum of the angles of a triangle is 180

A+ B+ C = 180

2x+5x+11x = 180

Combine like terms

18x = 180

Divide by 18

18x/18 = 180/18

x = 10

Angle A = 2x = 2*10 = 20

Angle B = 5x = 5*10 = 50

Angle C = 11x = 11*10 =110
