Find the exact value of sin (O)

12/13

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin O = opp / hyp

So we need to find the hypotenuse

Using the Pythagorean theorem

a^2 + b^2 = c^2

5^2 + 12^2 = c^2

25+144= c^2

169 = c^2

Taking the square root

13 = c

sin O = opp / hyp

sin O = 12/13

50-60=10

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
