N SRS of 21 students at UH gave an average height of 5.5 feet and a standard deviation of .1 feet. Construct a 90% confidence interval for the mean height of students at UH. a) (5.462, 5.538) b) (4.250, 6.950) c) (5.328, 5.672) d) (5.492, 5.508) e) (4.000, 7.300) f) None of the abov

step-by-step explanation:

dong do iy iys a scram

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
