Question

if u =(x+17)° and v =(4x-7°, find u and v supplementary angles

Answer 1

Answer:

value of x = 34

u = 51 degrees

v = 129 degrees

Step-by-step explanation:

sum of supplementary angles = 180 degree

u + v = 180

u = x + 17

v = 4x - 7

x + 17 + 4x - 7 = 180

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 34

angles :

u = x + 17

  = 34 + 17

   = 51 degrees

v = 4x - 7

  =( 4 * 34 ) - 7

  = 129 degrees
