Question

Find x in the following fingure in the triangle , P =:45 degree , Q = (3x + 16) degree , R = 68 degree​

Answer 1

45+68+3x+16=180

3x+129=180

x=17

Answer 2

Answer:

17

Step-by-step explanation:

Angle sum of triangle : 180 degrees

equation : 45+68+(3x+16) = 180

3x+16 = 180-45-68

3x+16 = 180-113

3x = 67-16

3x = 51

x = 51/3

x = 17
