Solve the equation for the red variable(C)in R-C=P

Greetings: 
<span>x² + y² + 8x + 22y + 37 = 0
(x² +8x) +(y² +22y) +37 = 0

</span>(x² +8x+4²)-4² +(y² +22y+11²) -11²+37 = 0
(x+4)² +(y+11)²-16-121+37 =0

(x+4)² +(y+11)² =10²...(<span>standard form )

Answer:

The measurement of angle HBC is m∠HBC=61°

Step-by-step explanation:

The given problem states that

The line BH divides angle EBC into two equal parts,

consult the attached diagram for clarity

thus

m∠EBC=m∠EBH+m∠HBC

where m∠EBH=m∠HBC

therefore

m∠EBC=2(m∠EBH)

Insert the provided values to solve for a

Determine the value of angle EBH

m∠EBH=(4(4)+45)=61°

Keep in mind that

m∠EBH=m∠HBC

therefore

The measurement of angle HBC is m∠HBC=61°

Perimeter (P)= 2Length (L) +2Width (W)
P=2L + 2W
P=(2y)+(3y-5)
P=5y-5
