The right hand tail of the standard normal curve can be defined as the part that lies at least 2 standard deviations to the right of the mean. according to the empirical rule, approximately what percentage of the area under the whole curve is in the right hand tail? round your answer to the nearest tenth.
a) 16%
b) 0.1%
c) 5%
d) 2.5%

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
