Question

12. The measures of the angles of a triangle are shown in the figure
below. Solve for x.
M. x = 48°
N. x = 42°
O. x = 222°

the answer is N but explain why

Answer 1

To solve for x, we can set up an equation using the fact that the sum of the angles in a triangle is always 180°.

In this case, we have:

x + 2x + (4x - 18) = 180

Simplifying the equation:

7x - 18 = 180

Adding 18 to both sides:

7x = 198

Dividing both sides by 7:

x = 198/7

Simplifying:

x = 28.3°

Since none of the given answer options match this value, the correct answer cannot be determined based on the given information.
