Answer:
False
Step-by-step explanation:
For AD and AC to be opposite rays they must be on the same straight line in opposite directions.
The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
Step-by-step explanation:
75 is equal to opposite angle of x.
so,
75° +65°+ x=180°( by all angles sum)
140°+x=180°
x=180°-140°
x=40°
