Answer:
Step-by-step explanation:
Id QS bisects angle PQR, then <PQS = <SQR and <PQS+<RQS = <PQR
The formula then becomes
<PQS+<PQS = <PQR
2<PQS = <PQR
<PQS = <PQR/2
Given <PQR = 119°
Substitute into the resulting expression above;
<PQS = <PQR/2
<PQS = 119/2
<PQS = 59.5°
Since <RQS = <PQR, hence <RQS is also 59.5°
The axis of symmetry is the x value of the vertex
we have a handy-dandy way of finding that from standard form, ax^2+bx+c=y
for
ax^2+bx+c=y
the x value of the vertex is -b/2a
y=-2x^2+12x-3
-b/2a=-12/(2*-2)=-12/-4=3
x=3 is the axis of symmetry
Square root of 18 because it's the only irrational number.
