Find the measure of FEG 25,65,80,90

lozanna [386]

Answer:

First, you have to set 5x equal to (3x+10). They are vertical angles and therefore congruent.

5x = 3x+10 The variable should only be on one side of the equation,

5x - 3x = 10 Therefore subtract 3x from both sides

2x = 10 Divide by 2 on both sides.

x = 5

We're not done yet, since we've found the x-value we have to solve for ∠GEC.

∠GEC = 3x+10 = 3(5)+10 = 15+10 = 25°

∠GEC and ∠FEG form a right angle. This means that the sum of the two angles is 90°

90° = 25° + x In this case, we're using "x" to solve for ∠FEG

90-25 = x We subtract 25 from both sides to get the variable by itself.

65° = x

∠FEG = 65° The Answer is B

If today’s UV index is 8, Erin will burn in 15 minutes without sunscreen. If Erin puts on lotion with an SPF of 25, how long wil

yan [13]

Today’s UV index is = 8

Erin will burn in = 15 minutes

Since, its given"The time it takes to burn without sunscreen multiplied by the SPF, or sun protection factor, is the time you can stay in the sun safely with sunscreen"

= $25\times15=375$

So, Erin will be protected for 375 minutes.

Explain why arctan(1) = 45° or π/4.

Answer:

Explanation below

Step-by-step explanation:

Inverse Trigonometric Functions

They are defined as the inverse of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant.

The corresponding inverse functions are called arcsin, arccos, arctan, arccot, arcsec, arccsc.

These inverse functions in trigonometry are used to get the angle with any of the trigonometry ratios.

For example,

$\displayystyle \sin 30^\circ=\frac{1}{2}$

Then:

$\displaystyle arcsin \frac{1}{2}=30^\circ$

Since:

$\tan 45^\circ=1$

Or, equivalently:

$\displaystyle \tan \frac{\pi}{4}=1$

Then:

$\displaystyle arctan(1)=45^\circ$

Or:

$\displaystyle arctan(1)=\frac{\pi}{4}$
