Sec θ = 1/cosθ

sec 19° = 1/cos19°

≈ 1/0.9455 ≈ 1.0576 ≈ 1.058

Answer:

The value of sec 19° = 1.058

Step-by-step explanation:

the value of the sec 19° using your calculator

use trigonometric ratios to find sec(19)

we know that sec(A) = 1/cos(A)

So sec(19)= 1/ cos(19)

now find the value of cos(19) using calculator

sec(19)= 1/ cos(19)= 1.058

The value of sec 19° = 1.058

Assume cos T = .45 and cos W = .89, both T and W are positive, and both T and W determine a terminal point in Quadrant 4. which

emmainna [20.7K]

As both $T$ and $W$ determine terminal points in the fourth quadrant, we know that both angles fall between $270^\circ$ and $360^\circ$ . We also know that $0$ for $270$ , and that $\cos x$ is strictly increasing along this interval.

This means that the angle with the larger cosine value must be closer to having a measure of 360 degrees than the angle with the smaller cosine value, so $W>T$ .
