Answer 1

Answer:

28

Step-by-step explanation:

SUM OF ALL ANGLES IN THE TRIANGLE = 180

5X-60+2X+40+3X-80 = 180

10X-100 = 180

10X  = 180+100

10X = 280

X = 280/10

X = 28

VEIFICATION:

5X-60 = 5(28) - 60 = 140-60 = 80

2X+40 = 2(28) + 40 = 96

3X-80 = 3(28) - 80 = 4

80 + 96 + 4 = 180

THERE FORE X = 28
