Answer:

2

Explanation:

To find the value of tan(theta) + sec(theta) when sin(theta) is equal to 6/10, we can use trigonometric identities.

First, let's find cos(theta) using the Pythagorean identity:

sin^2(theta) + cos^2(theta) = 1

Given that sin(theta) = 6/10, we can find cos(theta):

(6/10)^2 + cos^2(theta) = 1

36/100 + cos^2(theta) = 1

cos^2(theta) = 1 - 36/100

cos^2(theta) = 64/100

cos(theta) = ±8/10

Since cosine is positive in the first and fourth quadrants, we'll take the positive value:

cos(theta) = 8/10 = 4/5

Now, we can find tan(theta) and sec(theta):

tan(theta) = sin(theta) / cos(theta) = (6/10) / (4/5) = (6/10) * (5/4) = 30/40 = 3/4

sec(theta) = 1 / cos(theta) = 1 / (4/5) = 5/4

Finally, we can calculate tan(theta) + sec(theta):

tan(theta) + sec(theta) = (3/4) + (5/4) = 8/4 = 2

So, the value of tan(theta) + sec(theta) when sin(theta) is equal to 6/10 is 2.
