we know that
<u>in the triangle PQR</u>
m∠PQR+m∠QPR+m∠QRP=180°------> the sum of the internal angles of a triangle is equal to 180 degrees
(m∠PQR+m∠QRP)+74°=180°-------> (m∠PQR+m∠QRP)=106°
we know that
If QS and SR are angle bisectors
then
<u>In the triangle QSR</u>
m∠SQR+m∠QSR+m∠QRS=180°-------> equation 1
and
(m∠SQR+m∠QRS)=106°/2--------> (m∠SQR+m∠QRS)=53°
substitute the value of (m∠SQR+m∠QRS)=53° in the equation 1
53°+m∠QSR=180°
m∠QSR=180°-53°-------->m∠QSR= 27°
therefore
<u>the answer is</u>
The measure of angle QSR is 27 degrees
3m-9=9+3m
add 9 to both sides
3m=18+3m
minus 3m both sides
0=18

the best discription would be an empty solution set
Well, 10 percent of 2.50 would be 0.25. If you add 0.25, to the original cost it equals 2.75. Bella would have spent 2.50 originally.
x = 9
Hope this helps you :)
Answer:
vol of cylinder = per. of base x height + 2 (area of base)
area of base = pi x r^2
4pi = pi r^2
4=r^2
r=2
per of base = 2 x pi x r
2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)
4pi + 2(4pi)
4pi + 8pi
<u>12pi = volume</u>
