Find c to two decimal places and find the measure of angle B. Angle A = 58°, Side AC = 5, Side BC = 8, Find side C. Angle C is 9

KATRIN_1 [288]

Answer:

c = 9.43
m∠B = 32°

Step-by-step explanation:

Side c = AB can be found using the Pythagorean theorem:

c² = a² + b² = 8² +5² = 89

c = √89 ≈ 9.43

Angle B is the complement of angle A, so is ...

B = 90° -A = 90° -58° = 32°

c is approximately 9.43; the measure of angle B is 32°.

Pavel [41]

Answer:

5, 6, 7

(5 + 6 + 7)/3 = 6

<u>Standard deviation:</u>

σ = $\sqrt{((5 - 6)^2+(6-6)^2+(7-6)^2)/3} = \sqrt{2/3}$

Correct choice is d

-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5

(-5 -4 - 3 - 2 - 1 + 0 + 1 + 2 + 3 + 4 + 5)/11 = 0

<u>Standard deviation:</u>

σ = $\sqrt{((-5)^2+(-4)^2+(-3)^2+(-2)^2+(-1)^2+0^2+1^2+2^2+3^2+4^2+5^2)/11} = \sqrt{10}$

Correct choice is d

3, 4, 5, 6, 7

<u>Standard deviation:</u>

σ = $\sqrt{((3-5)^2+(4-5)^2+(5-5)^2+(6-5)^2+(7-5)^2)/5} = \sqrt{2}$ ≈ 1.4

Correct choice is d
