Question

Solve for X .. I know it’s two questions but I’m having a hard time

Answer 1

Unfortunately I can't do the first one, but the second one is easy

Explanation:

To find X in the Q) 11:

1. The triangle is an equilateral traingles meaning angles add up to 180°

2. Add the numbers - 2x - 9 + 3x + 2x = 7x -9

3. Add 9 to 180 (your adding because you changed the side of the number) - 189 = 7x

4. Divide 7 by 189

Your answer is x = 27

Answer 2

x = 35, x = 27

Explanation:

(9)

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

141° is an exterior angle, thus

x + 24 + 2x + 12 = 141 , that is

3x + 36 = 141 ( subtract 36 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

-----------------------------------------------------------

(11)

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

Sum the 3 angles and equate to 180, that is

2x - 9 + 3x + 2x = 180

7x - 9 = 180 ( add 9 to both sides )

7x = 189 ( divide both sides by 7 )

x = 27
