A male lion needs as much as 15 pounds of food each day or 105 pounds of food each week.how much does a lion need in one year.

You just need to multiply 105 by the number of weeks in a year. I'm not sure, but I think a year has 52 weeks, which means that your answer is the product of 105 times 52. Hope this helps.

In ΔBCD, the measure of ∠D=90°, the measure of ∠C=83°, and DB= 1.3feet. What is the length of CD to the nearest tenth of a foot.

Lina20 [59]

Answer:

$CD\approx0.2$

Step-by-step explanation:

By the tangent ratio, $tanC=\frac{DB}{CD}$ . Substituting the given values into this equation gives us:

$tan83$ ° $= \frac{1.3}{CD}$

$CD*tan83$ ° $=1.3$ (Multiply both sides of the equation by $CD$ )

$CD=\frac{1.3}{tan83\textdegree}$ (Divide both sides of the equation by $tan83\textdegree$ )

$CD=0.15962\approx0.2$

Hope this helps!

[Right Triangle Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

We have a right triangle. We can use trig to find the angle.

Step 2: Identify Variables

Angle = x

Opposite = 15

Hypotenuse = 23

Step 3: Find Angle x

Substitute: sinx° = 15/23
Inverse: x° = sin⁻¹(15/23)
Evaluate: x = 40.7057°
