Given cot A=5/2 and that angle A is in quadrant I, find the exact value of sin A in simplest radical form using a rational denominator

Given cot A = 3 over 7 and that angle A is in Quadrant I, find the exact value of cos A in simplest radical form using a rational denominator ... √58=c. cos = 3/√58 To rationalize, multiply the numerator and denominator by √58 ... how do i go about solving a trig identity; that simplify s 1-sin^2 theta/1-cos theta.

Step-by-step explanation:

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
