From the given figure, We can notice that :

∠BCA + 110° = 180° (Because they make a Linear Pair)

⇒ ∠BCA = 180° - 110°

⇒ ∠BCA = 70°

We know that : Sum of the Angles in a Triangle should be equal to 180°

⇒ 2g° + 9g° + ∠BCA = 180°

⇒ 11g° + 70° = 180°

⇒ 11g° = 180° - 70°

⇒ 11g° = 110°

g° = 10°

9g° = (9 × 10) = 90°

2g° = (2 × 10) = 20°

Answer:

g = 10

Explanation:

First, let's find the missing value of the 'C'

180 - 110 = 70 degrees

Now that we have the answer for one side, we can make an equation:

2g + 9g + 70 = 180 (area of a triangle is 180 degrees)

11g + 70 = 180

11g = 180 - 70

11g = 110

g = 110 / 11

g = 10

The value of g is 10 so we can now add them to the expression:

2g = 2(10) = 20

9g = 9(10) = 90

To make sure that you have the correct answer, add the values so that you get an answer as 180:

70 + 20 + 90 = 180

hope this helps....
