In ΔABC, m∠B = m∠C. The angle bisector of ∠B meets AC at point H and the angle bisector of ∠C meets AB at point K. Prove that BH
solniwko [45]

Answer:

See explanation

Step-by-step explanation:

In ΔABC, m∠B = m∠C.

BH is angle B bisector, then by definition of angle bisector

∠CBH ≅ ∠HBK

m∠CBH = m∠HBK = 1/2m∠B

CK is angle C bisector, then by definition of angle bisector

∠BCK ≅ ∠KCH

m∠BCK = m∠KCH = 1/2m∠C

Since m∠B = m∠C, then

m∠CBH = m∠HBK = 1/2m∠B = 1/2m∠C = m∠BCK = m∠KCH   (*)

Consider triangles CBH and BCK. In these triangles,

  • ∠CBH ≅ ∠BCK (from equality (*));
  • ∠HCB ≅ ∠KBC, because m∠B = m∠C;
  • BC ≅CB by reflexive property.

So, triangles CBH and BCK are congruent by ASA postulate.

Congruent triangles have congruent corresponding sides, hence

BH ≅ CK.

1. The 2006 General Social Survey contains information on the number of hours worked by a respondent each week. The mean number
Vilka [71]

Answer:

A)σ_M = 1.2634

B) CI = (36.564, 41.516)

C) σ_M = 0.1151

Step-by-step explanation:

A) Formula for standard error is;

σ_M = σ/√n

We are given;

Mean; x¯ = 39.04

Standard deviation; σ = 11.51

Sample size; n = 83

Thus;

Standard error; σ_M = 11.51/√83

σ_M = 1.2634

B) formula for confidence interval is;

CI = x¯ ± z(σ_M)

z is critical value

At 95% Confidence interval, z = 1.96

Thus;

CI = 39.04 ± 1.96(1.2634)

CI = (39.04 + 2.476) and (39.04 - 2.476)

CI = (36.564, 41.516)

C) sample size is now increased to 10000

Thus,standard error is calculated as;

σ_M = 11.51/√10000

σ_M = 0.1151
