Answer:
Option D (180°-m∠2)
Step-by-step explanation:
we know that
m∠1+m∠2=180° ------> equation A (by supplementary angles)
m∠3+m∠2=180° ------> equation B (by supplementary angles)
m∠1=m∠3 -----> equation C (by vertical angles)
Solve for m∠1 in equation A
m∠1=180°-m∠2
Remember that
m∠1=m∠3
so
m∠3=180°-m∠2
therefore
m∠1=180°-m∠2
m∠3=180°-m∠2
The expression that represent the measure of both angle 1 and angle 3 is
(180°-m∠2)
The answer is 6 because a=8

Answer: 96.2%
Step-by-step explanation:
Assume that the heights of American men are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = heights of American men.
µ = mean height
σ = standard deviation
From the information given,
µ = 69.0 inches
σ = 2.8 inches
the probability of men that have heights between 64 and 78 inches is expressed as
P(64 ≤ x ≤ 78)
For x = 64,
z = (64 - 69)/2.8 = - 1.79
Looking at the normal distribution table, the probability corresponding to the z score is 0.037
For x = 78,
z = (78 - 69)/2.8 = 3.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.999
Therefore,
P(64 ≤ x ≤ 78) = 0.999 - 0.037 = 0.962
Therefore, the percent of men meeting these height requirements is
0.962 × 100 = 96.2%
