Measuring by using Trigonometry
liberstina [14]

Answer:

x approximately = 11.971, y approximately = 0.837

Step-by-step explanation:

the 12 ft is the hypotenuse of the right angle triangle formed

Cos (theta) = adjacent/hypotenuse

so Cos(4) = x/12, solving for x = 11.971

Sin(theta) = opposite/hypotenuse

so Sin(4) = y/12, solving for y = 0.837

liq [111]

Answer:

Probability that all winner are men = 0.0035 (Approx.)

Step-by-step explanation:

Given:

Number of women = 50

Number of men = 26

Total number winner = 5

Find:

Probability that all winner are men

Computation:

Total competitor = 50 + 26 = 76

Probability that all winner are men = 26/76 x 25/75 x 24/74 x 23/73 x 22/72

Probability that all winner are men = 7,893,600 / 2,216,980,800

Probability that all winner are men = 0.0035 (Approx.)

25 points please help!
AnnZ [28]

Answer:

x= 10

Step-by-step explanation:

If line m is parallel to line n,

(8x +50)°= 130° (corr. ∠s, m//n)

8x +50= 130

Bring constants to one side:

8x= 130 -50

8x= 80

Divide both sides by 8:

x= 80 ÷8

x= 10
