Given: m∠EYL=72° Find: mEHL , mLVE

White raven [17]

Answer:

Part 1) The measure of arc EHL is $108\°$

Part 2) The measure of angle LVE is $54\°$

Step-by-step explanation:

step 1

Let

x-----> the measure of arc EHL

y----> the measure of arc EVL

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

$m$

we have

$m$

substitute

$72\°=\frac{1}{2}(y-x)$

$144\°=(y-x)$

$y=144\°+x$ ------> equation A

Remember that

$x+y=360\°$ -----> equation B ( complete circle)

substitute equation A in equation B and solve for x

$x+(144\°+x)=360\°$

$2x=360\°-144\°$

$x=216\°/2=108\°$

Find the value of y

$y=144\°+x$

$y=144\°+108\°=252\°$

therefore

The measure of arc EHL is $108\°$

The measure of arc EVL is $252\°$

step 2

Find the measure of angle LVE

we know that

The inscribed angle measures half that of the arc comprising

Let

x-----> the measure of arc EHL

$m$

we have

$x=108\°$

substitute

$m$

PLZ HELP!! Algebra is not my thing, 30 points!! 5x + 2 = 3x + 4(2x - 1)

ira [324]

Answer:

$5x + 2 = 3x + 4(2x - 1) \\ 5x + 2 = 3x + 8x - 4 \\ 3x + 8x - 5x = 2 + 4 \\ 6x = 6 \\ \boxed{x = 1}$

For the function given, state the middle line; f(t) = 40cos (80t + 20)

Digiron [165]

In the standard form of the equation

$\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\$

The middle line =k

For our given problem

f(t) = 40cos (80t + 20)

On comparison we get k=0

Hence middle line=0
