Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)

Eduardwww [97]

Given:

The figure of a right triangle. $PO=12,m\angle O=y^\circ$ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

$\sin\theta=\dfrac{Perpendicular}{Hypotenuse}$

In the given right angle triangle,

$\sin y^\circ=\dfrac{7}{12}$

$y^\circ=\sin ^{-1}\dfrac{7}{12}$

$y^\circ=35.685335^\circ$

$y^\circ\approx 35.69^\circ$

Therefore, the measure of angle y is $y^\circ =35.69^\circ$ .

The length, l, that a spring is stretched varies directly as the amount of force, F, applied to the end of the spring. When a fo

Elina [12.6K]

Answer:

C. 4.5 inches

Step-by-step explanation:

Given the following data;

Force, F = 10 pounds

Extension, e = 3 inches

First of all, we would determine the spring constant (k) using the following formula;

Force = spring constant * extension

10 = spring constant * 3

Spring constant = 10/3

Spring constant = 3.33 pounds per inches.

Next, we would find the extension of the spring when a force of 15 pounds is applied;

F = ke

15 = 3.33 * e

Extension, e = 15/3.33

Extension, e = 4.5 inches.

Show that sinxtanx=1-cos^2x/cosx

yawa3891 [41]

LHS: = $\sin x \tan x = \frac{\sin x \sin x }{\cos x} = \frac{\sin^2 x}{\cos x}$ (using $\tan x = \frac{\sin x}{\cos x}$ )

We know $\sin^2x + \cos^2x = 1 \Rightarrow \sin^2x=1-\cos^2x$ so we can replace the sin²x in the LHS expression as follows

$\frac{\sin^2x}{\cos x} = \frac{1-\cos^2x}{\cos x}$ which is the RHS.
