Using angle measures in triangles

solve for x. angle p is 25 angle r is 20 and angle q is 3x

x = 45

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. The angles in the given triangle are

Angle p is 25

angle r is 20

angle q is 3x

Therefore,

Angle p + angle r + angle q = 180

25 + 20 + 3x = 180

45 + 3x = 180

Subtracting 45 from the left hand side and the right hand side of the equation, it becomes

45 - 45 + 3x = 180 - 45

3x = 135

Dividing the left hand side and the right hand side of the equation by 3, it becomes

3x/3 = 135/3

x = 45
