It’s -4 and below since -4 is greater than x
Step-by-step explanation:
a)
82+OCE=90°{ tangent}
0CE=8°
OCE=OEC (base angle of isosceles triangle r equal}
8+8+a=180°(sum of angle of triangle)
a=180-16
a=164°
b)d+BEC=180°
BEC=122°
BEO=BEC-OEC
b=114°

Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately
