Given: circle k(O), mAM=125°, mEF=31°, m∠MAF=75° Find: m∠AME

myrzilka [38]

Answer:

The measure of angle A.M.E is $58\°$

Step-by-step explanation:

step 1

Find the measure of arc M.E

we know that

The inscribed angle is half that of the arc it comprises.

$m$

we have

$m$

$arc\ E.F=31\°$

substitute the values

$75\°=\frac{1}{2}(arc\ M.E+31\°)$

$150\°=(arc\ M.E+31\°)$

$arc\ M.E=150\°-31\°=119\°$

step 2

Find the measure of arc A.F

we know that

$arc\ M.E+arc\ E.F+arc\ A.F+arc\ A.M=360\°$ -----> by complete circle

substitute the values

$119\°+31\°+arc\ A.F+125\°=360\°$

$119\°+31\°+arc\ A.F+125\°=360\°-275\°=85\°$

step 3

Find the measure of angle A.M.E

we know that

The inscribed angle is half that of the arc it comprises.

$m$

substitute the values

$m$

The lateral area of a cone is 555 \pi cm^2 and the radius is 15.1 what is the slant height?

pishuonlain [190]

We know that
[LA]=pi*r*l
where
LA is the lateral area of the cone
r is the radius
l is the slant height
l=LA/(pi*r)
r=15.1 cm
LA=555*pi cm²
l=(555*pi)/(pi*15.1)----> l=36.75 cm

the answer is
the slant height is 36.75 cm
