Answer:

$m\angle KLM=53.13^o$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle KOM

In the triangle KOM

we have

$KO=MO=r=5\ units$

$KM=8\ units$

Applying the law of cosines

$8^2=5^2+5^2-2(5)(5)cos(KOM)$

$64=50-50cos(KOM)$

$50cos(KOM)=50-64$

$50cos(KOM)=-14$

$cos(KOM)=-14/50$

$m\angle KOM=cos^{-1}(-14/50)$

$m\angle KOM=106.26^o$

step 2

Find the measure of the arc KM

we know that

$arc\ KM=m\angle KOM$ ----> by central angle

we have

$m\angle KOM=106.26^o$

$arc\ KM=106.26^o$

step 3

Find the measure of angle KLM

we know that

The inscribed angle is half that of the arc comprising

$m\angle KLM=\frac{1}{2}[arc\ KM]$

we have

$arc\ KM=106.26^o$

substitute

$m\angle KLM=\frac{1}{2}[106.26^o]$

$m\angle KLM=53.13^o$

Answer:

$\frac{1}{4}$ left

Step-by-step explanation:

The question says she used $\frac{1}{2}$ of it, so she probably used $\frac{1}{2}$ of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:

$\frac{3}{4}$ - $\frac{1}{2}$

make denominators equal

( $\frac{2}{2}$ × $\frac{3}{4}$ ) - ( $\frac{1}{2}$ × $\frac{4}{4}$ )

$\frac{6}{8}$ - $\frac{4}{8}$

$\frac{2}{8}$

$\frac{1}{4}$
