Question 1(multiple choice worth 2 points)

(09.03)

in circle a below, ∠bae ≅ ∠dac.

what is the med?
82°
87°
98°
164°

Given ∠ BAE = ∠ DAC
=> the two angles are vertical angles
=> BAD and CAE are both straight lines.

Also given
12x-10 = ∠ BAE = ∠ DAC = 5x+53
=>
12x-10=5x-53
Solving for x gives
12x-5x=53+10
=> x=9
=> ∠ BAE = ∠ DAC = 9*12-10 = 98 °

Since BAD is a straight line, 
∠ BAE and DAE are supplementary, 
=>
BAE + DAE = 180 °
=> ∠ DAE=180-BAE=180-98=82 °
=>
Measure of arc ED = 82 °

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
