Question

In the triangle below, suppose that m∠W=(7x-5)° , m∠X=(3x-2)°, and =m∠Y=x°

Find the degree measure of each angle in the triangle.

Answer 1

Note that the internal angles of any triangle must sum to 180 thus 7x-5+3x-2+x=180 which yields x=17 degrees. Thus 7x-5=114 and 3x-2=49.

Answer 2

The sum of interior angles for any triangle is 180

so; 7x -5 + 3x -2 +x = 180. (combine like terms)

11x -7 = 180. (cancel 7)

11x = 187

x= 17

So, m∠Y=x° = 17.

Please plug x into the equations (7x-5)° and (3x-2)° to find these angles. If you need more assistance, please let me know
