In ΔPQR, \overline{PR} PR
is extended through point R to point S, \text{m}\angle QRS = (7x+8)^{\circ}m∠QRS=(7x+8)
∘
, \text{m}\angle RPQ = (x+12)^{\circ}m∠RPQ=(x+12)
∘
, and \text{m}\angle PQR = (3x+20)^{\circ}m∠PQR=(3x+20)
∘
. Find \text{m}\angle RPQ. m∠RPQ.
i'll really appreciate any answers lol

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
