What is the gcf of 25 and 90

Yuliya22 [10]

25 = 5^2
90 = 2 . 3 . 3 . 5

GCF is not as greedy as LCM.
GCF is just on a diet, so it takes the same number and the smallest amount.

25 and 90 both have 5.
5^2 or 5 ?
Take the smaller one.
GCF = 5

Use a calculator to solve for theta in the given interval

Allushta [10]

Answer:

d. $1.82\: or\:4.46$

Step-by-step explanation:

The given trigonometric equation is;

$\sec \theta=-4.0545$

Recall that;

$\cos \theta=\frac{1}{\sec \theta}$

$\implies \cos \theta=\frac{1}{-4.0545}$

$\implies \cos \theta=-0.2466$

The cosine function is negative in the second and third quadrant.

$\theta=\pi-\cos^{-1}(0.2466)\: or\:\pi+\cos^{-1}(0.2466)$

$\theta=1.82\: or\:4.46$
