Find the missing angle. 40° 80° X What is the missing angle?

Natali5045456 [20]

Answer:

60°

Step-by-step explanation:

Sum of angles of triangle = 180°

x + 40 + 80 = 180

x + 120 = 180 {Subtract 80 from both sides}

x = 180 - 120

x = 60°

How do you find arc ab

Marta_Voda [28]

Use trigonometry to find the angle between the segments 3 and 6.
∠XOB = arccos(3/6) = 60°

The measure of arc AB is double that angle, since the figure is symmetrical about the line containing the segment of length 3.

m(arc AB) = 2·60° = 120°

What is the value of x in the equation below?

belka [17]

$remember$
$ln(a^b)=bln(a)$
$ln(e)=1$
$so$
$ln(e^x)=xln(e)=x$

$1+2e^{x+1}=9$
$minus \space\ 1 \space\ both \space\ sides$
$2e^{x+1}=8$
$divide \space\ both \space\ sides \space\ by \space\ 2$
$e^{x+1}=4$
$take \space\ ln \space\ of \space\ both \space\ sides$
$ln(e^{x+1})=ln(4)$
$(x+1)ln(e)=ln(4)$
$x+1=ln(4)$
$minus \space\ 1 \space\ from \space\ both \space\ sides$
$x=ln(4)-1$
$answer \space\ is \space\ C=ln(4)-1$
