%of 25 is 14. what percent of 20 is 11? 15 is

ikadub [295]

The first question:

'is' in mathematics means equal
'of' in mathematics means multiplication

$\frac{x}{100} \times 25 = 14\\\\\frac{x}{4} = 14\\\\\boxed{\bf{x=56}}$

56% of 25 is 14.

And the second question:

'is' in mathematics means equal
'of' in mathematics means multiplication

$\frac{x}{100} \times 20 = 11\\\\\frac{x}{5} = 11\\\\\boxed{\bf{x = 55}}$

55% of 20 is 11.

Suppose cot(theta) = 5/12, where pi < theta < 3pi/2. What is sin(theta)?

trasher [3.6K]

Answer:

- 12 /13

Step-by-step explanation:

Given that:

Cot(θ) = 5 /12 ;

Recall ; cot θ = 1 / tan θ ; tan θ = sin θ / cos θ

Hence ;

tan θ = 1 / cot θ

tan θ = 1 ÷ (5 / 12)

tan θ = 1 * 12 /5 = 12/5

Tan θ = opposite / Adjacent = 12 /5

Sin θ = opposite / hypotenus

Hypotenus = √(opposite² + adjacent²)

Hypotenus = √12² + 5²

Hypotenus = √(144 + 25)

Hypotenus = √169

Hypotenus = 13

Hence,

Sin θ = opposite / hypotenus = 12 / 13

pi < theta < 3pi/2 lies in the 3rd quadrant ; SinΘ will be negative ;

Sin θ = - 12 /13

Given: ABC is a right triangle with right angle C. AB=14 centimeters and m∠A=33∘ .

ruslelena [56]

AC is the adjacent leg to angle A, so use cosine to find out AC
cosA=AC/AB
AC=AB*cosA
AC=14*cos33
use your calculator to find AC≈11.7
